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…
We had a bad CrowdStrike update years ago where their network scanning portion couldn’t handle a load of DNS queries on start up. When asked how we could switch to manual updates we were told that wasn’t possible. So we had to black hole the update endpoint via our firewall, which luckily was separate from their telemetry endpoint. When we were ready to update, we’d have FW rules allowing groups to update in batches. They since changed that but a lot of companies just hand control over to them. They have both a file system and network shim so it can basically intercept **everything **
