I think... crowdstrike made a global software release that is broken, causing machines to brick/bootloop - thats bad
But the cloud machines with crowdstrike are doing the same thing, thats worse
I wouldn't call this a supply chain attack, but more of supply chain incompetence. Like if a iphone update bricked iphones... slow rolling updates exist to avoid this very scenario, the ability to do a/b boots (if a doesn't boot, boot to b), etc.
