Countless theories for the cybersecurity firm’s outage are flying around, but whatever the reason, this sort of thing is likely to happen again • Don’t get TechScape delivered to your inbox? Sign up for the full article here “Where did CrowdStrike go wrong” is, if anything, a slightly overdetermined question. We can work backwards. Pushing an update to every single computer on your network at the same time means that by the time you discover a problem, it’s too late to limit the fallout. The alternative – a staged rollout – would see the update pushed to users in small groups, usually accelerating over time. If you begin by updating 50 systems at once, and then immediately lose all contact with every single one of them, hopefully you spot it before you update the next 50m. Continue reading...

This blog is now closed, you can read more on this story here There is a further update on the situation at the Port of Dover in England, which was mentioned earlier (see 9.41am BST). Chief executive Doug Bannister told the PA news agency: We operate a turn up and go system here. However, we do insist you have a book on busy days, even if people are doing this on the drive down. The greater visibility we have the better. But we are here to service people who want to travel. So I would say to displaced airport passengers ‘come on down. We have the capacity’.” We start to get busy about 5 or 5:30 in the morning. We’ve opened new infrastructure today which is working really well. So far there is no congestion in the town of dover. Approach roads are busy but moving. Everything is running well.” The worst of this is over because the nature of the crisis was such that it went very badly wrong, very quickly. It was spotted quite quickly, and essentially, it was turned off.” Until governments and the industry get together and work out how to design out some of these flaws, I’m afraid we are likely to see more of these again.
