The mistake was pushing it on Friday morning like a bunch of amateurs, they're supposed to push it out scheduled on Friday at 5:03PM so you have enough time to get to your car and off the parking lot
AFAIK it was a Thursday night push for people in US mountain time / pacific time. But, that ends up being Friday early morning in Europe and Friday mid-day in Asia.
An update to a cybersecurity software suite called CrowdStrike caused Windows machines to BSOD. CrowdStrike was big and monopolistic enough that it took out servees at large organizations worldwide.
Should have not trusted a third party to install proprietary code into the kernel. It's not a Windows issue directly, they have a Linux version too, but anything that allows third parties to put proprietary code into your kernel and automatically update it without your approval is untrustworthy.
The cause is a malfunction of the Crowdstrike monitoring solution, which employees use to spy at anything ever done on company hardware. They do have a Linux version and it has been reported to cause kernel panics (not sure if during this incident).
But yes, Windows on public information displays is dumb.
it was because crowdstrike themselves notified that this specific instance did not affect their linux nor osx distributions of security, and was windows specific.
