All our servers and company laptops went down at pretty much the same time. Laptops have been bootlooping to blue screen of death. It’s all very exciting, personally, as someone not responsible for fixing it.
Apparently caused by a bad CrowdStrike update.
Edit: now being told we (who almost all generally work from home) need to come into the office Monday as they can only apply the fix in-person. We’ll see if that changes over the weekend…

>Don’t test updates… for some reason??
I mean I know it’s easy to be critical but this was my exact thought, how the hell didn’t they catch this in testing?
Completely justified reaction. A lot of the time tech companies and IT staff get shit for stuff that, in practice, can be really hard to detect before it happens. There are all kinds of issues that can arise in production that you just can’t test for.
But this… This has no justification. A issue this immediate, this widespread, would have instantly been caught with even the most basic of testing. The fact that it wasn’t raises massive questions about the safety and security of Crowdstrike’s internal processes.
From what I’ve heard and to play a devil’s advocate, it coincidented with Microsoft pushing out a security update at basically the same time, that caused the issue. So it’s possible that they didn’t have a way how to test it properly, because they didn’t have the update at hand before it rolled out. So, the fault wasn’t only in a bug in the CS driver, but in the driver interaction with the new win update - which they didn’t have.
How sure are you about that? Microsoft very dependably releases updates on the second Tuesday of the month, and their release notes show if updates are pushed out of schedule. Their last update was on schedule, July 9th.
I’m not. I vaguely remember seeing it in some posts and comments, and it would explain it pretty well, so I kind of took it as a likely outcome. In hindsight, You are right, I shouldnt have been spreading hearsay. Thanks for the wakeup call, honestly!
Lots of security systems are kernel level (at least partially) this includes SELinux and AppArmor by the way. It’s a necessity for these things to actually be effective.
