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…
Why is it bad to do on a Friday? Based on your last paragraph, I would have thought Friday is probably the best week day to do it.
Most companies, mine included, try to roll out updates during the middle or start of a week. That way if there are issues the full team is available to address them.
