every single computer with crowd strike falcon on it might get this file and that can cause this outage. how can it be repaired? can i send out another update to be loaded onto all these machines around the world? the problem is that because it is the blue screen of death, you can't roll out another update to fix it, you have to manually have someone reboot the computer into what is known a safe move, delete the problem file and then reboot it again. forsome problem file and then reboot it again. for some systems, that is not possible. where they have promote management, people have to drive out to them, they have data centres are monitor is relatively quick to do this, when you are talking about thousands upon thousands of systems and it cannot be automated, the

suppose it also shows just how around the world, we are reliant on systems like this for every single bit of daily life that we are used to. you know, train services, going to. you know, train services, going to buy something at the supermarket. it is all about the convenience and speed of technology and this is the consequence when it goes wrong. particular when you have massive companies which widely deployed tools, when something small goes wrong, it can affect huge parts of the world, where is back in the old days, where it was more fragmented, it was a much more localised failure and that is easier to cope with. i have just seen our health editor speaking to one gp who says that we are only speaking to the most unwell patients and we are handwriting descriptions. thatjust brings home to you how reliant we are on these

computers. it to you how reliant we are on these commem— computers. it is actually quite impressive — computers. it is actually quite impressive that _ computers. it is actually quite impressive that they - computers. it is actually quite impressive that they are - computers. it is actually quite | impressive that they are doing computers. it is actually quite - impressive that they are doing the handwriting and they have maintained the manual processes because we need to keep those up today and that is exactly why. we are incredibly reliant. we are much less efficient without them, our communications go down, broadcasters are affected, and this is going to get worse before it gets better. just this is going to get worse before it gets better-— gets better. just explain, say for examle, gets better. just explain, say for example. a _ gets better. just explain, say for example. a tv — gets better. just explain, say for example, a tv channel, - gets better. just explain, say for example, a tv channel, how- gets better. just explain, say for. example, a tv channel, how would this affect what a whole channel going down? if this affect what a whole channel going down?— this affect what a whole channel auoin down? . ., . ., going down? if you have a collection of servers which _ going down? if you have a collection of servers which are _ going down? if you have a collection of servers which are producing - of servers which are producing broadcasting, they are generating the media and sending it out, and they are to have this tool on them and that file goes to them and they have a blue screen, none of those will be doing it any more. we will have some resilience in their may be dozens of different servers there is that if one fails, the others can pick them up, but when all of them

fail, because they are all running the same software, you have a problem. there is no back—up different software. so problem. there is no back—up different software. 50 i problem. there is no back-up different software. so i suppose, as ou sa , different software. so i suppose, as you say. it — different software. so i suppose, as you say. it is _ different software. so i suppose, as you say. it is the — different software. so i suppose, as you say, it is the way _ different software. so i suppose, as you say, it is the way that _ you say, it is the way that technology has changed. in the old days, say for example with a credit card payment, used to be a paper version of that but as we have moved more and more to computers, all of that back—up has gone. find more and more to computers, all of that back-up has gone.— that back-up has gone. and of course, that back-up has gone. and of course. atms _ that back-up has gone. and of course, atms may _ that back-up has gone. and of course, atms may be - that back-up has gone. and of course, atms may be affectedj that back-up has gone. and of. course, atms may be affected as well. cash machines. if shops are affected and people cannot use card, getting cash might be difficult. it is just the constants reliance on fewer and fewer technology providers leaves us in this position where we are incredibly vulnerable and incredibly affected by very small flaws which inevitably will happen. james, just lay with me because i want to bring you another couple of lines that we are having. the airline klm says they have suspended most operations. american airlines, the worlds biggest by passenger numbers has told the bbc that no

flights are currently being allowed to take off and it is in contact with all flights are currently in the air and the it problems it is facing are due to the technical issues with crowdstrike falcon impacting multiple carriers. the airline says it is working with the it security firm to fix a problem as quickly as possible. an interesting point. that american airlines are making, that they are in contact with all the planes that are actually in the air.- with all the planes that are actually in the air. yes, that will be usin: actually in the air. yes, that will be using different _ actually in the air. yes, that will be using different software. - be using different software. probably older software and different systems because there are systems we build that are so critical that you cannot use standard consumer and air traffic control is one of their setups. yes. control is one of their setups. yes, of course- — control is one of their setups. yes, of course- do _ control is one of their setups. yes, of course. do you _ control is one of their setups. yes, of course. do you see _ control is one of their setups. yes, of course. do you see this - control is one of their setups. yes of course. do you see this problem getting worse before it gets better because companies will be going in and turning computers on or turning self checkouts on as they come in and it tries to boot this new update that has the corrupt file on? it

depends whether this has been dealt with at source. we won't know that until we either get reports that they are now starting to be fined or not. it can be difficult to do because this is a file that is hostess statement hosted across a large number of places. to prevent has been done, you'd have to update all of those nights difficult in its own right. i do see there will be problems continuing new problems arriving over the next few days before things start getting sorted out. ., , ., ., , out. for viewers who have 'ust “oined out. for viewers who have 'ust joined fl out. for viewers who have 'ust joined us, james, i out. for viewers who have 'ust joined us, james, remind h out. for viewers who have just joined us, james, remind us i out. for viewers who have just i joined us, james, remind us what out. for viewers who have just - joined us, james, remind us what we believe has happened and the applications of it well. fit, believe has happened and the applications of it well. a driver file, a applications of it well. a driver file. a file _ applications of it well. a driver file, a file that _ applications of it well. a driver file, a file that help _ applications of it well. a driver file, a file that help certain - file, a file that help certain hardware or software to work on your computer, deployed by crowdstrike falcon which is a cyber security tool used to protect computers from attacks appears to have been corrupted somehow, we don't know

exactly how yet, and when a computer tries to boot with it, it puts into what is known as a blue screen of death, where you cannot do anything. this requires a manualfix, by a person to recover from. this requires a manualfix, by a person to recoverfrom. it this requires a manualfix, by a person to recover from. it is not as simple as rolling back the update or sending out a new update. it requires someone to actually interact with the computer and since this is such a widely used tool in important systems, this is having a lot of knock on effect.— important systems, this is having a lot of knock on effect. james baugh, a chartered — lot of knock on effect. james baugh, a chartered security _ lot of knock on effect. james baugh, a chartered security professional. . a chartered security professional. thank you for explaining that to our viewers around the world. appreciate our time viewers around the world. appreciate your time to — viewers around the world. appreciate yourtime to put _ viewers around the world. appreciate your time to put into _ viewers around the world. appreciate your time to put into perspective - your time to put into perspective how that one file is causing these problems around the world. if you are just tuning problems around the world. if you arejust tuning in. it is global it problem and it is affecting a lot of industries and businesses. we have, around the world, a lot of problems in airports. some flights are being grounded. we heard that american airlines out grounding flights. but a lot of airlines are having to say,

hong kong are already telling us they are doing manual check—in, there are issues, as i said. japan, india, spain, germany, prague, the united kingdom, the us, it really is spreading in terms of airports and airlines. we have supermarkets whose checkouts who would have that file in it and are getting that blue screen of death, the windows blue screen of death, the windows blue screen of death means they are not operating and we have been hearing it here in the uk that hospitals and doctors surgeries are not able to access pension notes and they are only seeing in the most sick people in one gp there are health editor was talking to and actually having to physically go back to pen and paper to write out prescriptions. as james was saying, a lot of industries don't have that manual back—up and are really reliant on this technology. we of course have correspondence you are working to try and get to the bottom of how

many places are affected. what i want to do is take you live to jerusalem and see how israel is coping. our correspondent is there. what is the latest from you there on how israel is coping with the it outage? how israel is coping with the it outa . e? ~ ., how israel is coping with the it outaae? ~ ., , , outage? we are still getting news about how things _ outage? we are still getting news about how things are _ outage? we are still getting news about how things are affected - outage? we are still getting news l about how things are affected here, but we understand that some of the postal services have been affected, as well as some news that the airport has said there might be delays in flights, but that is due to delays link to the outage elsewhere. the biggest effect is on hospitals, as you have been reporting. the health ministry has put out a statement saying that 15 hospitals have been affected and have switched to manual work, but it seems they have the ability to do that relatively smoothly because they say that the medical treatment of patients in the hospital's has not been affected. although the

ministry of health has instructed the evacuation of patients to other facilities that are not experiencing this malfunction. they are also saying, the ministry of health, that they are working with the global company to work to restore the lost programme, but they are doing so also with local solutions. they are trying to figure out their own ways of fixing this technical problem. although they are also working with a global company. that is the latest we have year from a global company. that is the latest we have yearfrom israel on how things are developing. ilil" things are developing. our correspondent _ things are developing. our correspondent in _ things are developing. our correspondent in israel and jerusalem. our correspondence are working around the globe to get is the latest. this from our wall saw correspondent. the baltic hub in the city of gdansk is the latest structure there to be affected. they are struggling because i have a microsoft operating system and it is

hampering terminal operations. they have asked companies not to send containers to the port. it began operating in 2007 and can handle up to 2.9 million containers there. another industry being hit. the latest from poland correspondent. let me update you with what we know. there is a major it outage reported around the world. many flights have been grounded, airlines and particularly affected by this. we are seeing that some airlines are having to resort to manual check—in, american airlines, the worlds biggest in terms of the number of passengers, it actually carries, have grounded all their flights. they have given us a statement blaming this on a technical issue with crowd strike. if you have been with crowd strike. if you have been with us to the last half an hour, we had the security expert explaining

the crowdstrike falcon is used to protect computers from cyber attacks and what he believes has happened as they were rolling out a new file as part of that system and it was corrupt or there was something wrong with that file and that is what has caused this problem. they do say that they have got an issue, but they have not said what it is. we have had no confirmation of that from crowdstrike itself. it does seem to suggest that this file has caused problems because we have seen a lot of microsoft operating systems giving the blue screen of death, which will mean that they have to be, according to that security expert, manually rebooted with the file taken out of it. this could cause problems. not only today, but going on around the next few days, he thought. we will keep you updated with the latest hear on bbc news.

and we can get the latest now from nick marsh who is in singapore and has been monitoring the latest. as we have been on air in the last half an hour, more airlines are saying they have problems, more shops say they have problems, more shops say they have problems and more hospitals and it really is spreading around the world, this problem, isn't it? it around the world, this problem, isn't it? , , . around the world, this problem, isn'tit? . , . isn't it? it seems that any organisation _ isn't it? it seems that any organisation or _ isn't it? it seems that any organisation or system i isn't it? it seems that any i organisation or system which isn't it? it seems that any - organisation or system which uses microsoft and is some way linked to this crowdstrike falcon piece of cyber security software is being affected and screens around the world are turning blue. we have seen it here in singapore. a colleague of mine who wasjust it here in singapore. a colleague of mine who was just downstairs saw it on an advertising hoarding, we have seen on airports, flights and their display screen, we have seen in banks, in supermarkets, this really is a completely global issue. i was just listening to the expert that you had on earlier, nicky, who

suggested that the only solution would be a manual solution, a manual reboot. it is notjust a case of updating or patching up the corrupt piece of software. if that is indeed the case and that has not been confirmed by microsoft or from crowdstrike, thatjust expert analysis there, if that is indeed the case then it means that we are looking at a very, very prolonged difficulty in many parts of the well, aren't we?— difficulty in many parts of the well, aren't we? absolutely. nick, 'ust well, aren't we? absolutely. nick, just outline _ well, aren't we? absolutely. nick, just outline where _ well, aren't we? absolutely. nick, just outline where you _ well, aren't we? absolutely. nick, just outline where you have - well, aren't we? absolutely. nick, just outline where you have heard| just outline where you have heard that being issues at the moment. here in singapore, we have her that the airports are doing manual check—in, but no planes have been grounded yet, just delays to the check—in process. a major newspaper here, the website was down for a while but it does seem to have come back up. the newsroom where i am now and am speaking to you from, so far, we have not had any issues so far.

in terms of further afield in the region, sydney airport also experiencing pretty bad delays, my colleague was just updating you, wasn't he? saying there were long queues, but things seem to be slowly but surely resuming. from further afield, in the united states, united airlines and delta have taken a step of grounding all of their aircraft because there is significant problems going on there. in the uk, as i am sure you know, problems and all of the london airports, some train services and companies have also reported issues, though train services so far seem to be operating reasonably normally, correct me if i'm wrong there. also health services, you know, doctors only seen the most unwell patients, and writing prescriptions and the nhs is also said it is facing difficulties there as well. the london stock exchange, i could go on, they have said they had outages but things

seem to have resumed. that doesn't seem to have resumed. that doesn't seem to have resumed. that doesn't seem to be any rhyme or reason to be quite frank as the who is hit and when or if they manage to resolve the issues. when or if they manage to resolve the issues-— when or if they manage to resolve the issues. . ,, , ., ~ ., the issues. nick, thank you, i know ou will the issues. nick, thank you, i know you will monitor _ the issues. nick, thank you, i know you will monitor the _ the issues. nick, thank you, i know you will monitor the situation - the issues. nick, thank you, i know you will monitor the situation there from singapore. developments coming in all the time. let me update you with some of the latest. we have been talking about airlines, we're hearing that bar codes at gatwick airport are not working and port who operate a lot of baggage handling and airport say that the it outages are affecting a number of their sites as well. let's get the latest. as far as you know, what at the moment we believe has caused this? here is what i think is going on. they're either one or two issues that have either combined to make a perfect storm or are connected together and it is looking increasingly like they are

connected. microsoft says it has been investigating an issue with its services and apps in particular its cloud service in the us. we have also got a company called crowdstrike. there are lots of reports this company is an antivirus company. it is used by lots of people and there are reports that it has pushed out an update which has badly affected pcs and devices running microsoft software, which is obviously an awful lot of them because millions of people around the world use things like microsoft 365. so it is looking like either a combination of those two things or those two things are connected and thatis those two things are connected and that is what has caused this problem. often when you hear about an outage, by the time you have had the chance to think that is annoying it has rebooted and everything is fine and it is gone away. i don't think we're going to see this in this case. even if the core issue itself is resolved, the knock—on effect we are seeing this morning is so considerable that it will take quite a while i think for everything to settle down and get back to

normal. and i think lots of people are going to find that
