The CrowdStrike software at fault operates at what’s called the kernel level of a computer, a much deeper level than what more ordinary applications such as browsers or video games do.
For businesses with hundreds or thousands of laptops, desktops and servers running CrowdStrike’s security software, an individual human may have to perform that process over and over and over again.
Because CrowdStrike’s security software is running on countless individual computers all around the globe, the update that got pushed to those devices caused them all to shut down, virtually simultaneously.
The CrowdStrike bug may have initially been conflated with the Microsoft issue because CrowdStrike’s error affected only Windows machines.
As of Friday morning, Microsoft said the issue with Microsoft 365 had been resolved and that the situation was improving.
