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 we blame MS at least as much? How does MS let an update like this push through their Windows Update system? How does an application update make the whole OS unable to boot? Blue screens on Windows have been around for decades, why don't we have a better recovery system?

Crowdstrike runs at ring 0, effectively as part of the kernel. Like a device driver. There are no safeguards at that level. Extreme testing and diligence is required, because these are the consequences for getting it wrong. This is entirely on crowdstrike.

This didn't go through Windows Update. It went through the ctowdstrike software directly.
