surgeries are affected. and the national pharmacy association says services in community pharmacies, including the accessing of prescriptions from gps and medicine deliveries, are disrupted. to the high street, where the bakery chain gail's says it's been unable to take in store payments. this branch in london saying it was only accepting click and collect orders. banks including santander and metro bank have also reported disruption to their systems. and the supermarket morrisons said earlier it had payment problems in some stores which have now been resolved. the outage has also reached the comfort of the living room. blue peter was replaced by birdsong on the cbbc channel and there was intermittent broadcasting from sky news. a major global it outage is hitting businesses worldwide, including here at sky news. the cause? microsoft says...

that third party platform, the global cybersecurity firm crowdstrike which says the outage is... this is very much a global issue. police in the us state of alaska say their 911 emergency phone lines have been affected. supermarket checkouts in australia have crashed, and the outages hit security machines during preparations for the paris olympics, forcing staff to carry out manual checks. as and when systems get back online, it is not clear whether it will be business as usual or if it will take some time for all those impacted to clear the backlog. nickjohnson, bbc news. our transport correspondent katy austin

is at heathrow airport. the technical outage has hit travel around the world, affecting many airlines and airports. british airways and ryan are just some of the carriers are unable to use their it systems as normal. edinburgh airport stopped accepting incoming flights, people were asked to leave. at amsterdam schiphol airport, the disruption has been huge. klm suspended most operations. flights have been taking off and landing at heathrow, britain's busiest airport, but there are delays and cancellations on one of the busiest days of the year here. among those affected has been american airlines and here it he threw terminal three, for a while people were turning up to be told they could not drop off

again, it will take time for things to get back to normal. lucy, what is the latest on the disruption being caused to flights in and out of the uk? $5 caused to flights in and out of the uk? �* , , ., caused to flights in and out of the uk? ~ , y ., a, caused to flights in and out of the uk? as you were hearing in katie's iece uk? as you were hearing in katie's piece there. _ uk? as you were hearing in katie's piece there, around _ uk? as you were hearing in katie's piece there, around 100 _ uk? as you were hearing in katie's piece there, around 100 flights - uk? as you were hearing in katie's. piece there, around 100 flights have been cancelled in and out of the uk and globally around 11100 have been cancelled. it is really the delays that are the story, that has been the main issue, that people are being majorly delayed but also the question is will come later when people will miss their interconnecting flights. speaking to american airlines in the terminal here that they were saying earlier that people were not allowed to drop bags off because of issues, people have to do things manually by writing things out by hand and we heard from colleagues in delhi saying flight information was on whiteboards and people having to write their boarding passes out by hand. the issues are the delays and when people start missing those interconnecting flights what will

happen then. we were hearing earlier about edinburgh airport stopping some flights, that is back up and running but the knock—on effect is still going on and will be going on for some time. we were hearing about berlin airport earlier being shuts. in terms of the uk, this was expected to be the busiest weekend for people going off on holiday since before the pandemic, so many people looking forward to those holidays abroad that they have been waiting for and now they are facing huge delays. in terms of what people are allowed to do if they are delayed, the airline has this duty of care to them and because this is an extraordinary event, you probably won't get a refund for your flight but they have a duty of care to get you there, so they should be getting you there, so they should be getting you there, so they should be getting you there at some point and that could be putting you on another airline, but in the meantime they should give you food vouchers, drinks vouchers, maybe even a phone data so you can keep in touch. it is

important you keep your receipts for that sort of thing so you can claim it back after. and also some advice to people who had emergency medicine they take with them on holiday, put it in your hand luggage, not in the hold, because they could be issues with bags some people have been advised not to bring bags to the hold at all, just travel just to be sure with your hand luggage. in terms of the airport here at heathrow, when a major event happens, often what happens is the hotels get booked up very quickly but that has not happened yet and it seems to be several hours of delays at the moment. we are not seeing things here turning into hotel bookings just yet but it is the interconnecting flights that people are missing so this will go on and on because of those issues we are

expecting to keep seeing over the coming days. expecting to keep seeing over the coming days-_ expecting to keep seeing over the coming days. lucy, thank you very much for that _ coming days. lucy, thank you very much for that update. _ coming days. lucy, thank you very much for that update. as - coming days. lucy, thank you very much for that update. as we - coming days. lucy, thank you very much for that update. as we have | much for that update. as we have been hearing... the it outage has caused severe problems here in the uk with problems in retail, on the railways, and in the nhs where most gp surgeries in england are unable to access many services, including booking patient appointments. how has this impacted people? we have how has this impacted people? - have heard about japan, india, have heard aboutjapan, india, australia but it is important to see how it has affected people here in their daily lives, cafes have to close down because they cannot take payments, i've been trying to speak to people affected, spoke to one gp who said i am doing what i used to do years ago, issuing prescriptions ijy do years ago, issuing prescriptions by hand and it is frustrating because it is taking a lot longer than printing them out as i usually would. a local business in buckinghamshire that has had to

close because it has been unable to take electronic payments and says is worried about the local economy and what extent this will make it my profit margin. i havejust come back from covid in terms of my business, it is doing well now and i'm worried will have a detrimental effect on its revenue going forward. surrey nhs foundation has declared a critical incident due to the it outage saying the issue has affected its it system we use it to deliver radiotherapy this morning, so obviously radiotherapy is being used to treat cancer patients and patients being told they came out will not take place which puts pressure on those who are keen to have the treatment take their serious illness. —— treat their serious illness. —— treat their serious illness. —— treat their serious illness. in education, some teachers are struggling and they are having to adapt and do different things. we are not sure how long this impact will go on for. we know

there is a solution but the backlog in the nhs has been there for years, we know the nhs is struggling and just one day of cancelled appointments will obviously put pressure on the system and exacerbate those delays. it is not clear how long the impact will go on for, but i'm being told by some people that they anticipate there is going to be a domino effect for a few days yet at least. find going to be a domino effect for a few days yet at least.— few days yet at least. and also, what is incredible _ few days yet at least. and also, what is incredible about - few days yet at least. and also, what is incredible about this - few days yet at least. and also, what is incredible about this is i few days yet at least. and also, i what is incredible about this is the fact it is impacting so many different areas of life, as you mentioned, gp surgeries, shops, banks. , . , , mentioned, gp surgeries, shops, banks. , , a mentioned, gp surgeries, shops, banks. , , banks. yes, absolutely. as you said, it is impacting _ banks. yes, absolutely. as you said, it is impacting travel, _ banks. yes, absolutely. as you said, it is impacting travel, education, - it is impacting travel, education, health. just some breaking news from around five minutes ago, the devolved department of health in belfast said around two thirds of gp practices in northern ireland have been affected by the outage, the practices are unable to access patient records, generate

prescriptions or see the results of lab tests and that is very important stuff if you are a patient who once your test results and have been anticipating them and you have been told they are delayed, who knows how that would affect you. we know patients with minor illnesses are being sent to pharmacies instead of gp surgeries. one doctor said pharmacies are experiencing delays, prescriptions as the systems are down and some wholesalers are experiencing it system failures too. so you might think life hasn't been impacted, at the moment you might be thinking things are going smoothly but maybe in the next few hours and the days to come you may experience some delays. this morning in my local town the cafes were closed and i was unable to go into a cafe to get my usual coffee because they are

unable to take electronic payment, so that is the micro level, if we look at a macro level you are looking at things like health care which obviously have a detrimental impact and will cause some worry to some people across the country. qm. some people across the country. 0k, aood to some people across the country. 0k, good to talk — some people across the country. ok, good to talk to you, thanks so much that update. around the world there are also issues. can we cross live to hugh schofield? we will try to go to him in paris to get the update, the olympics are starting in... a week today we will have the opening ceremony and the outages may have an impact on those. around the world and across the uk, this is bbc news.

more now and those global it outages. as i mentioned earlier, paris is hosting the olympics a week today and there has been impact on what is preparation for the olympics. the bbc�*s hugh schofield is following events from the french capital. what has been the impact of the outage on those preparations? there has been an — outage on those preparations? there has been an impact _ outage on those preparations? there has been an impact but _ outage on those preparations? there has been an impact but it _ outage on those preparations? there has been an impact but it has - outage on those preparations? ii—ii” has been an impact but it has been limited, that is the message from the organising committee. when news broke this morning about the it cuts, people very nervous and thought it might have a devastating effect at this critical point. what it has affected mostly it seems is accreditations for journalists, other officials, distribution of uniforms apparently has been slowed down. we have a colleague he was seeking to get accreditation this morning and she could not do it

because the it system was down. apart from that, the olympics committee is saying all the key work is going ahead as fine, the ticketing has not been affected, work at various sites around the centre of paris where we are now is not being affected, the olympic flame is proceeding on the last legs of its voyage around france. the only other thing that might be affected it is saying is the arrival of delegations. of course they are beginning to arrive now in france from around the world and because of problems with airlines it may be some of those are delays, but i think the short answer is the apprehensions and worries of this morning when this news first broke have not been realised, there is an impact but it has not been huge. thank you. let's return to london. the it outage has impacted banks and businesses around the world and has had an impact on the financial

world. our international business correspondent, theo leggett. what has the impact been on the financial sector? this what has the impact been on the financial sector?— financial sector? this has been a hue it financial sector? this has been a huge it outage- _ financial sector? this has been a huge it outage. it _ financial sector? this has been a huge it outage. it has _ financial sector? this has been a huge it outage. it has affected l huge it outage. it has affected everything from bakeries to banks. talking about banks, there are plenty of them in the buildings behind me and the financial industry is international by definition, so there have been a number of problems. we have seen banks in china, south africa, germany, they have all experienced problems. i'm told the banks in germany are getting back up to steam, in the uk as well. the london stock exchange where shares are traded in this country, they said they have not had too many problems but some information systems have gone down. elsewhere, it is trading platforms that things like oil and gas and electricity which have experienced issues. they are having problems. then you have other businesses. you

are talking earlier about the travel industry, it is notjust the day—to—day operations, their share prices as well. shares in airlines such as the parent company of british airways, easyjet, ryanair, they have seen share price falls and they have seen share price falls and the reason is people are worried about how long this will go on for and the kind of disruption it may cause to the travel industry over the coming days, the crucial days, the coming days, the crucial days, the start of the big summer getaway. and insurance companies have been suffering from falling share prices because there will be able to be for this. we don't know how serious the impact will be overall, but if compensation needs to be paid, it is the insurance companies who will pick up at least part of the tap. what about crowdstrike, the company who says it's the fact hit the operating systems, what about their share price?— share price? crowdstrike, we know their share — share price? crowdstrike, we know their share price _ share price? crowdstrike, we know their share price has _ share price? crowdstrike, we know their share price has fallen - their share price has fallen dramatically at the moment. they seem to be ultimately responsible for the outage. there will certainly be reputational damage for them,

whether there is financial damage, that will be sorted when we see the full impact of this outage over the coming days. full impact of this outage over the coming days-— full impact of this outage over the coming days. thank you very much indeed. reporting _ coming days. thank you very much indeed. reporting there _ coming days. thank you very much indeed. reporting there on - coming days. thank you very much indeed. reporting there on the - indeed. reporting there on the impact of the financial sector. i mentioned that the company crowdstrike, it is a cybersecurity firm and says a defect in one of its software updates hit windows operating systems. the impact of this has been so widespread and so quick and in many cases really quite worrying. we can talk about how this could happen in this way with our cyber correspondent. for those people who are not tech savvy and know what we are talking about, talk about the bare basics, how can this end up happening? it starts with crowdstrike which is a cybersecurity company, very well respected and trusted around the world, particularly by giant organisations, and that is why we have seen such a big impact and an

immediate impact because of the biggest companies in the world use crowdstrike and they have a very popular piece of software called falcon which is what we call an end point protection piece of software and it is like an antivirus software you would download and have on your home computer, but there is one of those witches for big companies, and they put out they hoped was an innocuous software update overnight. —— one of those which is for big companies. it is like one of those updates you would do automatically on your computer and you don't even really notice but this one had a flaw in it, there was something wrong with the code which was sent out to all of their customers and bearin out to all of their customers and bear in mind if they have 211,000 customers around the world, that is 24,000 customers around the world, that is 211,000 medium, small, large enterprises, so that is potentially hundreds of thousands of end points of computers that received this bad software update and somehow, on

windows, when the software update was downloaded to a windows computer, which most of them would have been, it broke the computer and meant you had this blue screen of death and that is what people are dealing with all over the world. it managers are now trying to get what has just been released managers are now trying to get what hasjust been released by crowdstrike, the correct antidote if you like, that piece of software, and they are trying to get that onto computers but the problem we have is that cannot be done automatically over the internet, it has to be done with a manual process in most cases, so that is physical, fingers on keyboards to try and solve the issue. ., ., ., , ., ~ issue. how long do you think it will take for the — issue. how long do you think it will take for the issues _ issue. how long do you think it will take for the issues that _ issue. how long do you think it will take for the issues that we - issue. how long do you think it will take for the issues that we have i take for the issues that we have seen to be solved, given what you are talking about on the fact this needs a physical reboot so to speak? i think it is really interesting, you would imagine the really large customers of crowdstrike who have thousands, maybe tens of thousands

of computers and servers on the networks, they have been affected, you would imagine they will take a long time but what we are actually saying is the opposite, some of the companies that are bouncing back up at the largest ones, american airlines for example, you would imagine they have thousands of computers across the world, they have bounced back pretty quickly and it points to the companies that are large and have lots of computers, they are well funded and have it departments that are well resourced, so they have bounced back and are appearing to bounce back quicker than perhaps the smaller businesses or medium sized businesses that do not have that well resourced it team, they may even outsource it to a third party. where we might see the real crunch point is where you have a large company that isn't well resourced in the it side, so they have lots of computers and not enough people to fix them. good to talk to you. — enough people to fix them. good to talk to you, thank _ enough people to fix them. good to talk to you, thank you _ enough people to fix them. good to talk to you, thank you very - enough people to fix them. good to talk to you, thank you very much i talk to you, thank you very much indeed. our cyber correspondent

there. more is always on the bbc live page if you want to step away from the tv and read a bit more about its outage. briefly some other news. are court in russia has found us journalist evan gershkovich guilty of espionage and sentenced him to 16 years in prison. he was arrested in march last year and russian investigators claim he was at the cia's request collecting classified information about a russian tank manufacturer. the prosecution asked for an 18 year sentence. and independent news website said the conclusion of the trial in a record short time give rise to speculation a swap deal between russia and the us involving evan gershkovich may be done in the nearfuture. we can evan gershkovich may be done in the near future. we can speak to our correspondence for more, talk us through what this now means for mr gershkovich. it through what this now means for mr gershkovich-— gershkovich. it means he and his defence team _ gershkovich. it means he and his defence team have _ gershkovich. it means he and his defence team have about - gershkovich. it means he and his defence team have about two - gershkovich. it means he and his i defence team have about two weeks gershkovich. it means he and his - defence team have about two weeks to appeal the verdict, otherwise he is set to be sent to the russian penal

colony of a specialist strict regime. we don't know where he will be spending his sentence. it is indeed a very swift and short court trial and it indeed raises speculation about the possibility of a close swap deal, because according to the russian lawyers, a person who is set to be introduced in this swap deal has to be pardoned by the president and due to be pardoned, a person has go through a trial and be sentenced. this person has go through a trial and be sentenced. , ., ., , ., , , person has go through a trial and be sentenced. , ., ., , , sentenced. this trial obviously has been called _ sentenced. this trial obviously has been called an _ sentenced. this trial obviously has been called an absolute _ sentenced. this trial obviously has been called an absolute charm - sentenced. this trial obviously has been called an absolute charm by| been called an absolute charm by those who work with evan, what do we know about the possibility of the swap? —— an absolute sham. do we think this what may happen at some point? to think this what may happen at some oint? ., , . ., ., , point? to be clear, the only thing that shows _ point? to be clear, the only thing that shows as _ point? to be clear, the only thing that shows as a _ point? to be clear, the only thing that shows as a swap _ point? to be clear, the only thing that shows as a swap deal - point? to be clear, the only thing that shows as a swap deal is - point? to be clear, the only thing| that shows as a swap deal is close is the fact the trial took only

three days in court, so all in all it was a month and usually those cases are heard for at least six months, so the fact that evan gershkovich has been sentenced so quickly does raise speculation that a swap deal is coming. however, vladimir putin has told a number of times to different media that he is ready to send evan home, only if the case of berlin, germany, allows them to send a russian back to russia. 0k, to send a russian back to russia. ok, thank you. there's more on that on the bbc news website. you are watching 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 too far away already coming into the western side of scotland and the reason for this heat as we have been dragging in this heat and humidity from the south, thejet this heat and humidity from the south, the jet stream this heat and humidity from the south, thejet stream has been buckled to the rest of us but now it is starting to gather and it will post those weather fronts across our shores. three tonight and tomorrow. at the moment, that southerly wind is still with us, the remnants of yesterday's weather front stuck across parts of scotland and northern ireland giving early fog but it is left on, drier and brighter on the whole but there is rain in the western isles through the day, could be an isolated shower further east across england and

wales but essentially a dry picture for the uk. more sunshine for scotland and northern ireland compared to yesterday but we might get into the high 20s and possibly 31 in the south and east which means a warm and humid feeling day, refreshing sea breezes around the coast but sunshine just as strong and really high humidity for sleeping. by the time we get through the night, the rain is already taking shape gradually, pushing across northern ireland, northern and western scotland and approaching the northern and western fringes of wales. that process continues through saturday, the devil any detail but it looks like there will be intense bursts of rain, thunderstorms as well mixed in with this and it could destabilise the atmosphere a little further east was, provide us with showers and thunderstorms. but for many central and eastern areas, still a lot of heat and and dry weather, so not great news, could be localised flooding. that progresses eastwards, that rain, through saturday night into sunday, so we may still wake up

with some of that thundery rain across eastern scotland, southern and eastern parts of england, but once that clears it is a drier window of weather, it is just how quickly that's clears and temperatures will have debt as well. behind that weather system, the humidity lower so a more comfortable night for sleeping sunday into monday but you may notice the next low pressure starting to move in off the atlantic to bring more rain for a time on monday. mixed bag going into next week for more detail as ever head through the website.

a major it outage cripples industries worldwide,
