and here at the bbc — children's channel cbbc experienced problems broadcasting. cyber correspondentjoe tidy gave this explaination of how the outages happened. some of the biggest companies in the world use crowdstrike. and they are, they have a very popular piece of software called falcon, which is what we call an end—point protection piece of software. so it's like an antivirus software that you would download and you would have on your home computer. but there's one of those that's for big companies, and they put out what they hoped was an innocuous software update overnight, which would have made their product a little bit better. just a small update, the kind of like when we get on our phones, on our mobile phones, we get software updates and we update them, don't we? we do it automatically normally while we're sleeping and we don't even really notice. but this one, um, obviously had a flaw in it. there was something wrong with the code that was sent out to all of their customers. and bear in mind, if they've got 2a,000 customers around the world, that's 2a,

add that the bbc, the children's channel cbbc experience problems broadcasting. they are now back.icrosoft 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 perh

in an aside, i am pleased to say that cbbc, our children's channel, is now back on air after being downnels that have problems but they are now back on air, i am pleased to say. we are covering the situation across the globe given this was a global it situation and we had this report from indira gandhi international airport in india from samir hussein. i'm at indira gandhi international airport and i am flying on holiday from delhi to kolkata with my family, and we are absolutely affected by this global outage. and what they're doing here is manually entering everybody�*s passenger information. now, complicating issues for myself is that my children don't have seat assignments just yet, so we're trying to work that out. now, if you want to just take a look at my boarding card, you can see that all the information had to be entered in manually. the same thing for baggage tags. they were all entered in manually, so it's anyone's guess whether or not i'm actually going to get the luggage at the end of this trip. but i will say that in terms of mood, people are getting a little bit snippy n

i should also say that our children's channel cbbc is also offer chat dilemma at the moment full stopt is the only one, crossed fingers, thatis is the only one, crossed fingers, that is currently affected. the big companies that are affected like microsoft will have teams of people trying to fix this as quickly as possible and roll out an update if they need to because their business relies on it being secure and keeping going 2a seven. the relies on it being secure and keeping going 24 seven. the services are bombarded _ keeping going 24 seven. the services are bombarded all— keeping going 24 seven. the services are bombarded all day _ keeping going 24 seven. the services are bombarded all day every - keeping going 24 seven. the services are bombarded all day every day - keeping going 24 seven. the services are bombarded all day every day with malware, people trying to do harm, people trying to hack stuff. they have pretty robust systems in place over something this catastrophic to happen at this scale is hugely unusual and it is something that must got through an awful lot of walls
