as snags affecting its services. it is understood to have been caused by a faulty update which was released by the cyber security company crowdstrike. the firm says it is deploying a fix. banks, supermarkets, and other major organisations reported computer issues disrupting services, with some airlines having to suspend flights, and airports worldwide are reporting delays for passengers, with several reverting to manual systems. where they are operating, pastors are being warned it may take time for them to take off because of backlogs with air traffic control. also, hospitals have been affected. many elective operations have been cancelled, as have patient consultations, with doctors reporting they have had no access to patient records. media organisations have also been affected. here in the uk sky news were fair. add that the bbc, the

children's channel cbbc experience problems broadcasting. they are now back. microsoft says it is a mess getting the issue which appears to be linked to the global cybersecurity firm crowdstrike, and it says it is taking mitigation actions. we have correspondence all over the world is monitoring the situation, but you are going to start with our cyber correspondence, who joins us live. where do we start? of course, we have had that statement from crowdstrike. the sea that they have got a fix in place, but when are we going to see the actual fix in real terms? it depends on the organisation. we are already seeing that fix being unfermented and large, well resourced, quite wealthy companies, like american airlines. they say they have managed to put that fix back on their machines and are back to basics where they were. but given an issue like this, especially with an issue like this, especially with an airline, there will be a backlog,

and delays will cause further chaos for days to come. but the issue we have this where there are large organisations that are perhaps under resourced in the it department. for example if you have tens of thousands of computers, or end points, you need to get all those us back up and running. i'm hearing that this is not the case of doing an automatic update in the same as that happens overnight. so the automatic update went out by crowdstrike on two computers around the world, and nobody had to do anything. this is a case of fingers on keyboards. this requires it technicians going to many of the computers, in fact most of the computers, in fact most of the computers, and getting theirfingers on the keyboards, doing a reboot, putting it into safe mode, downloading the new, correct crowdstrike update, to try and fix the problems. there are ways around that evidence for example a server, if there is a cluster of servers inside an it company, i am told it is possible to do this with some kind of over the air, over the internet site fix. but that is real,

and it still has to be done and everything a computer. although we now have a fix, the real problem is how do you get that fix onto computers. this is obvious the a headache for so many people, so many different companies. if you think about crowdstrike, they have 2a,000 customers, but those customers are absolutely huge. airlines, health services stop wide, how, does a company like this, that has 24% of market share, how do they roll out an update without testing it beforehand? i wonderjust what an update without testing it beforehand? i wonder just what went wrong? huge questions to be asked of this company when the dust settles. already we are seeing the company being hit with it hurts, on their share price. lost a fifth of their value already this morning, that is before some markets have opened. this is a company scrambling now not only to fix the current situation, but also their reputation and their brand. it was and is one of the biggest cybersecurity company is in the world, famous for its very good

and well trusted end point protection. the protection and computers the world. but it is all about trust. and that trust has been affected by today, no doubt. the irony here is is that inside cyber security we are always being told to install the updates, whether it is personally on our phones, our laptops, when an update comes in from apple or google for example, thatis from apple or google for example, that is because the updates are there to protect us, 30 fix any potential bugs, fill up any security gaps, and to make things run smoother. here are of course doing the right thing got you and lots of trouble. if you had automatic updates on with crowdstrike overnight, you would wake up to an issue here that is bringing down entire companies. yes, huge questions to ask of crowdstrike. the way these things work is that there will be a team of engineers that wrote this update, wrote the software, the court over the last few weeks or months, and that would be sent out last night after lots of checking. crowdstrike would have put it on to lots of computers and seen whether or not it affects anything.

somehow something has gone wrong in that safeguarding process. it has gone from the test—bed, the sandbox of the internal computers at crowdstrike, into the wider world, and because these massive problems. when you look at the kind of things affected, obviously it is microsoft, not linux, not mac. i wonder where the difference is in terms of what crowdstrike is offering? do they offer their services to mac or linux, or is itjust microsoft products, or is itjust a different system so they were not impacted by this updates? windows has been careful to distance itself from this problem. they are seeing, this is not our problem, not ourfault. it is seeing, this is not our problem, not our fault. it is the seeing, this is not our problem, not ourfault. it is the problem of course, they are helping to try fix this. they are saying it has nothing to do with our system, it is a crowdstrike issue. this is fear, when crowdstrike makes a new piece of software they have to make for

all the operating systems, windows, aqua to, linux. the reason why windows has proven the most difficult is because perhaps that is the largest group of customers that they have. they are running windows. for some reason, that is something to do with the bespoke code that is done from windows that is not affected linux are too. i would argue that there are probably fewer customers using those particular operating systems. people asking today, how does affect me question actually to watch out when i tell my computer? the answer probably not. crowdstrike has built its business through large enterprises, like airlines, responsible for thousands or tens of thousands of, usually windows computers. interestingly, i havejust spoken windows computers. interestingly, i have just spoken to an it manager who is scrambling around and stressed out, for a medium—sized organisation in this country, in the uk, and he is responsible for 4000 computers, but it has given me an idea of how

stressful it is for him. he says that once you are a fingers on keyboards on a computer, it is a quick fix. you have to press a few buttons, and it into safe mode, and then you can download the correct crowdstrike software and there are a the problem is, he says, we have computers across five different sites, you have to physically drive from one to the next to the next to fix this problem. it does put it into perspective. elon musk describing this as the biggest it deal ever. lattices comments, helpful comments. i think that is probably right. the closest we would get to this is 2017 with a cyber attack, a deliberate and malicious cyber attack, that affected about 300,000 computers hundred and 50 countries. but that was stopped. the virus stopped spreading. people could rebuild from there. what we are seeing here, if the it manager hasn't seen the news today, and they

are waking up, for example in the us, they turn on your computer, they are going to get the blue screen of death. the blue screen of death. we are all googling that. thank you so much for that. i was labour corresponded having a very business day. microsoft are saying that the underlying cause of this mass it outage has been fixed for its apps, but it is that residual impact which is continuing impact some services, and the company previous he had said this was due to an update from a third—party software platform, which as we now know has confirmed as crowdstrike. crowdstrike singh that they have implement a fix. but it will take time —— crowdstrike are seeing. including travellers, including travellers in berlin. we will travel now to speak to my colleague. a mixture of calm but annoyance given the amount of

disruptionjust annoyance given the amount of disruption just that annoyance given the amount of disruptionjust that one annoyance given the amount of disruption just that one airport? traditionally this airport is packed, queues are moving, but very slowly. what we are seeing, although it is crowded, it is a calm atmosphere i cannot see it is chaotic. but lots of concerned aces. everyone is on the phones, trying to contact airlines, get information, which is difficult, because the airlines themselves are overwhelmed, particularly some airlines such as ryanair are having particular rya nair are having particular problems. ryanair are having particular problems. the fans are, they are saying they are only minimally affected. 0ther saying they are only minimally affected. other parts of germany, frankfurt, i spoke to a person there, said they have not seen much disruption, good news. practically for international travellers,

because a lot of people from outside of germany will travel to frankfurt, move on to other destinations. that is positive. but berlin, earlier today all flights. to bradley. flights have now resumed. wejust saw a plane take off over there. that is a positive sign. things are slowly starting to move. what the airport authorities are seeing here and that some smaller airports, hamburg, cologne, dusseldorf, they are seeing it is going to be a lot of waiting around. i think the queues are going to be long. people are certainly keeping their eyes on the news, and try to contact airlines and airports to see if they need to make alternative arrangements. quite a stressful time for people who thought they were planning to just go on holiday today. yes, as we were hearing from simon calder, this is the busiest day of travel, because schools are breaking up, people trying to get away. that

was before all of this has been happening. we are getting update from edinburgh airport. people staying calm that they have at the airport is no longer accepting incoming flights that haven't already taken off. passengers whose flights have been cancelled have been asked to leave. 0nce flights have been cancelled have been asked to leave. once you are there at the airport, is there clarity on what people should do if their flight is delayed? are they being told to just wait? are they being told to just wait? are they being told to leave? it depends on the airline. what we are seeing is that some airlines, at burlington airport, some of the airlines have desks where information is being given out. some airlines don't have desks. then you are a light on a website, or if you are a light on a website, or if you are lucky, a call centre, which you might not get through to. it depends on the airline. the airport in berlin is sending lots of people around with high viz vests who are giving out information. i think what they are trying to do more is just calm people down, because it is a limit to how much information they

can get. the boards you are being updated on the time. it is quite clear that some of the airlines are saying, we are open for business, we are still going to run. some of the airlines are seeing, this is cancelled, you are going to have to go home. that is the difficulty. when i last ate the boards, about one third of flights cancelled. i will look in minutes, seemed the latest situation is. either way, it is one in four people. notjust today, obviously it has a knock—on effect over the next few days. that is what the authorities are cn, is that people need to keep an eye on their travel plans over the next few days because if planes end up in the wrong place, it does have a domino effect, it disrupts travel further down the line. lots of anxious travellers over the next few days, notjust today. days, not just today. really days, notjust today. really frustrated no doubt. thank you for bringing us up to date on the situation they are in berlin. talking about how you just got to

keep checking those boards, which is super frustrating. just an update from our transport correspondence, to give you an idea of the numbers of flights, the kind of the numbers of flights, the kind of impact that this it outage has had. according to a data company, as of around 1145 uk time, 1396 flights have been cancelled globally, and that figure is subject to change. this comes as over 110,000 commercialflights were this comes as over 110,000 commercial flights were scheduled globally today. the figures at the moment, 1369 flights cancelled globally. 110,000 commercialflights flights cancelled globally. 110,000 commercial flights were scheduled today, globally. when you look at it, this isjust early today, globally. when you look at it, this is just early doors, today, globally. when you look at it, this isjust early doors, the impact will be huge further down the line, especially if there is a later on cancellation, a knock on effect.

we have correspondents around the world monitoring what is happening. let's go to tokyo. you are a little bit later on in the day, so to speak, so bring us up—to—date on what is happening there. we've been hearing about the blue screen of death, how that is the big indication of the it outage and its effect on different companies and airlines and train lines. i am in shibuya, the heart of tokyo, famous for its screens, and behind me, they haven't been affected, they are still in full force. good news here. injapan, there have been localised affected areas. we have been on the phone to one of the biggest airports injapan, and the budget airlinejet starjapan has been affected and has had to cancel dozens of its flights.

we have also been seeing pictures of passengers in the airport, but also some in another smaller airport. it has a knock—on effect because it has delayed a lot of flights. in terms of crowds gathering around the desks, trying to be checked in manually. japan airlines has also experienced a glitch in the reservation management system that has to do with anything you are doing online or through the app. anything in terms of changing your flight or making new bookings or using yourfrequent flight or making new bookings or using your frequent flyer cards or apps, that has been suspended so far. of course, japan is where the bullet train is, and that hasn't been affected so far. we are keeping a close eye on that. it is the height of the tourism season but also the height of school vacations, because schools are out and families are travelling locally as well. the bullet train is key. so far, no

effects. we did hear of an train line in sakha that has been affected in terms of the technology —— 0saka. the trains themselves are working but there has been some disruption. 0ne but there has been some disruption. one big tourist destination in osaka is universal studios japan, a huge park. all the cash registers and anything to do with paying in shops and restaurants around the park, they have been affected and suspended. also some of the air conditioning systems as well. it is boiling and very humid here, and that has been a concern with the operators in the parks that have been handing people some cooling items and some water. as it stands here, i am seeing a lot of tourists. people are milling about in the heart of tokyo, but like i said, there are localised areas injapan have been affected, and that has

affected hundreds and hundreds of people so far. yes, those unseen repercussions with the air conditioning. for the time being, thank you very much. live from tokyo. we have correspondents all over the world and we will keep you up—to—date, so do stay with us here on bbc news around the world and across the uk. this is bbc news.

welcome back. you are watching bbc news. we are continuing to monitor the situation with his major global it outage. the company that issued that cybersecurity firm crowdstrike, that cybersecurity firm crowdstrike, that issued the update, says that a fix has been deployed, but as we've been hearing it will take a of time for that fix to reverberate throughout all the many different systems that have been impacted. let's get the very latest developments. 0ursenior let's get the very latest developments. 0ur senior uk correspondentjoins us from the

newsroom. bring us up—to—date. correspondent joins us from the newsroom. bring us up-to-date. we've been hearing — newsroom. bring us up-to-date. we've been hearing from _ newsroom. bring us up-to-date. we've been hearing from people _ newsroom. bring us up—to—date. ,, been hearing from people abroad how this it outage has affected those countries, but it has had a massive impact here. things that affect everyday life here, whether it is retailers, banks, schools, gp surgeries, all are seeing effects, and that is affecting real people, whether you are not able to get medication on time, not able to see their gp, not getting the information they need from their local schools for their children to attend that day, and that is having attend that day, and that is having a significant impact on everyday people. we have had a statement recently from royal surrey nhs foundation trust, and they have declared a critical incident amid a major it outage. a statement on their website says, royal surrey has declared a critical incident due to external it issues which are widely affecting services, including ours. this issue has affected first night,

the system we use for treatments. —— radiotherapy treatments. they have contacted patients to give them another appointment and they do have these systems will be up and running soon and will directly contact patients. that is an example of how it is having an impact on real people's lives. these are appointments that many patients will see as crucial ones, perhaps they have been gearing up four and now they are being cancelled. as you say, there is a fix but it will take time for that actually sink in. more information on the health service — patients with minor illnesses are being sent to pharmacies from gp surgeries, according to the chief executive of the independent pharmacies association. they say that pharmacies are experiencing delays in prescriptions arriving through gp systems as the systems are down and they are also seeing delays in receiving medicines in

stock due to wholesalers experiencing it system failure. i spoke to a gp a little while ago then they are saying that in some cases they are using pen and paper rather than printing out prescriptions, as we know they usually do. they are going back to the old way of prescribing people but it is what they are having to do because their system is down. we are not clear how many people it is affecting but we know that hundreds of gp surgeries, i think somebody even said that around 1000 gp surgeries have been affected by this outage. that is a lot of people gabbing to those surgeries. thank ou so gabbing to those surgeries. thank you so much _ gabbing to those surgeries. thank you so much for— gabbing to those surgeries. thank you so much for bringing - gabbing to those surgeries. thank you so much for bringing us - you so much for bringing us up—to—date. really important to stress, we have been talking about travel issues, but of course, systems in gp surgeries, all of those services that rely on microsoft are obviously impacted. you can get in touch with us if you have been impacted. we have a live page on our website where we are

focusing on all the different changing aspects of this story. let's cross over to lisa minute, travel editor at the sun newspaper. in terms of where you are, what is the impact? it looks like you are in a lovely place on holiday. congratulations for getting away before all of this. i congratulations for getting away before all of this.— congratulations for getting away before all of this. i have managed to escape- — before all of this. i have managed to escape. well _ before all of this. i have managed to escape. well done, _ before all of this. i have managed to escape. well done, it - before all of this. i have managed to escape. well done, it looks - to escape. well done, it looks stunning- _ to escape. well done, it looks stunning- in — to escape. well done, it looks stunning. in terms _ to escape. well done, it looks stunning. in terms of- to escape. well done, it looks stunning. in terms of viewersl stunning. in terms of viewers looking at the situation and thinking, my goodness, i should looking at the situation and thinking, my goodness, ishould be gabbing to the airport, what should they do? i gabbing to the airport, what should the do? ~ . gabbing to the airport, what should the do? ~' , ., they do? i think the first thing to do is to double _ they do? i think the first thing to do is to double check _ they do? i think the first thing to do is to double check with - they do? i think the first thing to do is to double check with your l do is to double check with your airline and your airport before you set off. there was due to be this weekend 1.6 million of us heading abroad. it is the busiest weekend of the year, and the busiest we can for flying since 2019. this will have a huge impact on customers in outputs. the likes of ryanair and whiz air

are saying it is at least three hours at the airport to go through. a lot of things will have to be done manually. people cannot check—in online. everything will have to be done at the airport, and that is leading to huge scenes of disruption that we are seeing across the country. with the railways, we have seen the same, in terms of ticket machines not working in people having to use ticket offices rather than machines. it will get a lot worse before it gets better. we heard from simon calder earlier, saying that companies like ryanair have said they will not charge you for printing out their boarding passes, which is really helpful and arguably necessary. in terms of if your flight has been cancelled, then, because of the ongoing knock—on effect of the earlier delays, what can a passenger do? i delays, what can a passenger do? i think the issue is the fact that the airline has a duty of care. there is

no compensation due because this is an extraordinary circumstance outside of the airlines' control. but they have a duty of care to look after you, but they have a duty of care to look afteryou, including but they have a duty of care to look after you, including some drinks and after you, including some drinks and a meal if you will be delayed significantly. if you are delayed overnight, includes getting you into a hotel. if yourflight overnight, includes getting you into a hotel. if your flight is cancelled completely, they should be getting you to your destination as quickly as possible. that doesn't necessarily mean with that airline. if you find they are saying, we can get to your destination in two days. if they can send you an alternative way, perhaps with a train or another airline, you can do that and claim it back through the original airline. ., , , , airline. no problems, 'ust solutions. i airline. no problems, 'ust solutions. lisa, �* airline. no problems, 'ust solutions. lisa, enjoy h airline. no problems, just solutions. lisa, enjoy the| airline. no problems, just- solutions. lisa, enjoy the rest of your holiday. thank you so much. we continue to monitor this developing story here on bbc news.

the heat and the sunshine will last another day for many parts, but already, change is afoot. today might well be the hottest day of the year so far, but there is rain not far away, already coming into the western side of scotland. the reason for the heat is because we have been dragging in this heat and humidity from the south. the jet stream has been buckled to the west but now it is starting to gather and it will push those weather fronts across our shores. tonight and tomorrow. at the moment, the southerly wind is still with us. the remnants of yesterday's weather front is across northern ireland giving drizzle and fog. it is lifting, but rain will come into the western isles through the day. there could be an isolated shower further east across england and wales. essentially, a dry pitch of the most of the uk. sunshine for parts of north—east scotland and northern ireland compared with yesterday. a pleasant 22 celsius, but we might get into the high 20s and possibly 31 celsius in the south

and possibly 31 celsius in the south and east, which means a warm and humid feeling day. some refreshing sea breezes on the coast, but the sunshine isjust sea breezes on the coast, but the sunshine is just as strong. an oppressive night with high humidity for sleeping. oppressive night with high humidity forsleeping. by oppressive night with high humidity for sleeping. by the time we get through the night, the rain is already taking shape, gradually putting across northern ireland, northern and western scotland and approaching the western fringes of england and wales. that process continues through the day on saturday. the devil is in the detail but it looks as if there will be intense bursts of rain, thunderstorms as well, mixed in with this, and it could destabilise the atmosphere a little further east and provide showers and thunderstorms here as well. there many and eastern areas, still a lot of heat and heat and humidity, and a lot of dry weather tomorrow. tomorrow, further west, there could be localised flooding. the rain progresses further east through saturday night into sunday. we may wake up with some of that thundery rain around across eastern scotland, southern and eastern parts of england, but on the whole, once that clears, it looks like a dry are window of

weather. it isjust looks like a dry are window of weather. it is just how quickly that there is a way, and temperatures will have date. behind that weather system, the humidity is lower. a more comfortable night for sleeping, sunday into monday. the next low pressure is starting to move in off the atlantic to bring more rain for a time on monday. a mixed bag going into next week. for more details, head to the website.
