Microsoft says it estimates that 8.5m computers around the world were disabled by the global IT outage.
It’s the first time a figure has been put on the incident and suggests it could be the worst cyber event in history.
The glitch came from a security company called CrowdStrike which sent out a corrupted software update to its huge number of customers.
Microsoft, which is helping customers recover said in a blog post: “We currently estimate that CrowdStrike’s update affected 8.5 million Windows devices.”
The downstream effects are likely much much greater. If an auth server/DB server/API server/etc (for example) got taken down, the failure cascades
The idea that any such servers would be running windows… shudder
In the corpo that I work in, we had about 3000 servers down, plus probably twice as many workstations including laptops of remote workers. Yeah, fun!
