of our colleagues, jeshua, one of our colleagues, joshua, reporting from luton airport, see after the delay to his eight o'clock take—off, eight o'clock local time, it is now midday local time here, he is pleased to see checkouts are now open for the flights to vilnius from luton. there is an update. well done, was here. we heard from jfk earlier and they said there were a few delays and they had been impacted. why are some airports are affected more than others? it airports are affected more than others? . , , ., others? it all depends on the extent to which your _ others? it all depends on the extent to which your systems _ others? it all depends on the extent to which your systems which - others? it all depends on the extent to which your systems which cover l to which your systems which cover everything from online check—in before you get to the airport to sorting out your baggage to the flight dispatch procedures. those will be stored somewhere in the cloud probably because that is the most efficient way to do it and therefore you are in a position if you are reliant on those for your

airport systems, then clearlyjfk, a key american airport, isn't but if you're one of the airlines that is affected and i'm looking here at cancellations for example on euro wings which is the budget version of lufthansa, they have cancelled flights from stuttgart to heathrow, then you are going to be badly affected and i'm afraid i am looking at luton airport cancellations here and we have already seen the wizz air to athens and to warsaw, those have been cancelled and really important flights at the start of the summer holidays and we could sadly see some later because of course all the airlines are working at full stretch and that is very little slack in the system. i5 at full stretch and that is very little slack in the system. is so frustrating _ little slack in the system. is so frustrating for _ little slack in the system. is so frustrating for all _ little slack in the system. is so frustrating for all of _ little slack in the system. is so frustrating for all of those - frustrating for all of those travellers and josh was saying that his name was ticked off a list, paper and pens in the age of ai,

course, assignment was saying, whose delays, the repercussions, pilots in the wrong places having done all that different hours and let's cross over to tokyo where shaimaa khalil isjoining us live now. you are ahead of us timewise so hopefully you can give us the lay of the land. is the situation resolving itself? what is happening there injapan? i am in the heart of tokyo in shibuya and this is an area famous for its screens and neon lights and as you can see around me, we thankfully don't have those blue screens, the neon lights and big screens of shibuya and this area which is famous for them are still in full force and it is a very hot and humid night but i am seeing travellers and tourists all around me and there has been an impact to this it outage but it has been concentrated in certain places so we have heard from narita airport and we have been on the

phone to them and the budget airline jet starjapan has been experiencing disruptions and has had to cancel dozens of its domestic flights and you were talking there about the summer holidays and families here are also getting ready for the summer holidays because schools are out so we have heard many families in narita airport is making those domestic flights to different parts of japan domestic flights to different parts ofjapan using jet starjapan having to be delayed and the company itself, they are checking in people manually again and all of the things that happened normally with your apps and on your phones or where you take your luggage to do it automatically, those have all halted, and we are hoping thatjapan airline is also experiencing a glitch and its online reservation system, so again, anything where you are making a booking or changing your booking or using your flight, cards for example, frequent flight cards, that has been on hold. also,

japan is famous for its train punctuality and the train linejr quest in osaka has been affected, not the trains themselves but the big screens and anything online that tells people or the screens that tells people or the screens that tell people where your trainer is taking off so there has been confusion in the station itself. one big tourist location has been affected, universal studios japan, and this is the height of the season here and we have heard from universal studios in osaka seeing all the registers and cache years and anything with the shops or restaurants, people have been unable to pay and also some of the eye conditioning systems have been affected and it is really hot here so they have been handing out water manually for people to keep cool so here in the heart of tokyo it looks and feels like business as usual but

there are certain areas around the country especially when it comes to jet starjapan and narita airport, they have been affected.- jet starjapan and narita airport, they have been affected. thank you for aaivin they have been affected. thank you for giving us _ they have been affected. thank you for giving us the — they have been affected. thank you for giving us the scope _ they have been affected. thank you for giving us the scope and - they have been affected. thank you for giving us the scope and scale i they have been affected. thank you for giving us the scope and scale of| for giving us the scope and scale of the impact there injapan. thank you to shaimaa khalil in tokyo. we obviously know that this is a global it event and crowdstrike, the company that has just given a statement saying they are actively working with customers impacted by a defect which was found in a single content update for windows hosts and mac and linux hosts aren't affected but what does that all mean? let's speak to a tech expert who is joining us live now, stephan hair. it is so embarrassing because it is actually so simple in one sense, crowdstrike which is a cybersecurity firm which tries to protect your phones devices like laptops did a

software update, so normally does things get rolled out and it got sent around the world because it has a 24% market share and a flawed security update has a massive impact globally, so that is what has happened, and the problem is that we think of fixing it will require a manualfix, e:g., people will have to go and actually tamper with their own computer, so that analysis at this point in time and that may change but it is notjust a case of crowdstrike updating the system again and rippling it out, this could have knock—on effects you today for quite a longtime. could have knock-on effects you today for quite a long time. going back to 2496 _ today for quite a long time. going back to 2496 market _ today for quite a long time. going back to 2496 market share, - today for quite a long time. going back to 2496 market share, how . today for quite a longtime. going back to 24% market share, how does that compare to other companies? it sounds enormous, a quarter of everything that uses this kind of stuff is provided by this one company? that is how many different companies, difference firms and organisations are impacted? yes. organisations are impacted? yes, the have

organisations are impacted? yes, they have around _ organisations are impacted? yes, they have around 24,000 - organisations are impacted? yes they have around 24,000 customers but the customers are not organisation so imagine it might be like a gigantic company counts as a customer which obviously means that gigantic company itself might have thousands of workstations and devices which are now being affected so that is why the number is so big and obviously because it is affecting microsoft office, how many others are using microsoft office? it is not affecting mac or linux which is interesting, and it is really a lesson for all of us in cyber resilience and people talk about that all the time, you have to plan for failure and have something called business continuity and we are unfortunately getting a painful test run of what that looks like and thatis test run of what that looks like and that is why you are seeing people having to literally revert to paper and pen and getting out markers and whiteboards in order to run a flight board and get customers and that is not ideal and that is why governments are getting involved because it is affecting things like hospitals as well as trains and all transport but again, not every

airport and not every hospital, and thatis airport and not every hospital, and that is good, because it means we have distributed the risk and used other providers and that is what you want to hear, but still a really big bucket check with this company so a problem with crowdstrike, if they get a cold the rest of the world falls it. ,,., , get a cold the rest of the world falls it. , , ._ , get a cold the rest of the world falls it. , , , ., falls it. said this is may be a wake-up _ falls it. said this is may be a wake-up call— falls it. said this is may be a wake-up call to _ falls it. said this is may be a wake-up call to the - falls it. said this is may be a wake-up call to the tech - falls it. said this is may be a - wake-up call to the tech industry or wake—up call to the tech industry or governments do not let one company monopolise so much? and just the points that linux and macs aren't affected, how does that work? it depends on what kind of operating system you are running and most people run microsoft, so that is why it is affecting, if you want microsoft office product which so many companies or organisations around the world to that is why it affects you, i am speaking to you from a mac, for instance, so i am good, we hope, you never know. what does this mean? first of all, you never want to rely on one single provider and we are seeing that and

thatis provider and we are seeing that and that is why many things are still working and not everyone is relying on crowdstrike at the moment but secondly, there is also the fact that when you run a software update, this should have been tested and this should have been tested and this should have been tested and this should never have happened and things go through all sorts of staging environments to make sure it is safe and that should have been done i crowdstrike's and so there will be questions for that company once we all get through this but we all want them to fix it now and do the clear up later. it also, perhaps for those of us on the receiving end of these things, that is where you could see big companies and governments making sure, how do we make sure this happens again? like when something is critical as a crowdstrike update comes through, do we want to test it ourselves in the staging environments post? fin we want to test it ourselves in the staging environments post? on that note, ou staging environments post? on that note. you have _ staging environments post? on that note, you have given _ staging environments post? on that note, you have given us _ staging environments post? on that note, you have given us a _ staging environments post? on that note, you have given us a lot - staging environments post? on that note, you have given us a lot of- note, you have given us a lot of food for thought and a fix been has been applied but we have to think about that resilience. don't go

anywhere. hello there. the heat and sunshine will last eight of date for many parts but already changes afoot. today it might well be the hottest day of the year so far but there is rain already coming into there is rain already coming into the western side of scotland and the reason for all this heat is because we have been dragging in this heat and humidity from the south and the jet stream has been buckle to the west of us but now it is starting to gather and it will push those weather fronts through our shores through tonight and tomorrow. so for the moment that soberly went still with us and the remnants of yesterday's weather front stuck across scotland and northern ireland giving some early morning mist and fog put this rate will come into the western isles through the day and there could be an isolated shower further east across england and wales but essentially a dry picture for the most of the uk. more sunshine for parts of scotland and northern ireland compared yesterday, so 20 two, that is pleasant, but we

could get warmer in the south and east which means a warm and humid feeling day with a sea breeze and an oppressive heat as well, high humidity for sleeping. and by the time we get through tonight, the rain is already taking shape, gradually pushing across northern ireland and western scotland and approaching the western edges of england and wales and that continues through the rest of the day and saturday and the devil is in the detail but it looks like they will be intense burst of rain with thunderstorms mixed in and that could destabilise the atmosphere a bit further eastwards and provide us with some showers and thunderstorms to put for many eastern areas that are still a lot of heat and humidity and drier weather but for the west, they could be some localised flooding, not great news. that rain continues through saturday night into sunday so we may wake up with that thundery rain still around eastern parts of england and scotland is put on the whole it looks like a drier window, it is

just how quickly that plays away and temperatures will have as well, behind that weather system, humidity low but so are more comfortable night for sleeping sunday into monday but you may have noticed the next low pressure starting to move on of the atlantic to bring more rain for a on of the atlantic to bring more rainfora time on of the atlantic to bring more rain for a time on monday and a mixed bag going into next week but for more details, as ever, you can head to the website.

luton. there is an update. well done, was here.

live from london, this is bbc news. a major it outage cripples industries worldwide, shutting down banking and retail systems, delaying trains, and grounding flights. a faulty update by the global security firm crowdstrike appears to be the cause of the problem. they see a fix has been deployed. but experts see a full resolution could take some time because each computer affected will need to be manually rebooted. this is the seen live in rome at one of the many airports where it problems mean issues with check ins. welcome to bbc news. businesses and institutions around the world have been knocked off—line because of a major it outage. microsoft says it is investigating what it describes
