Windows Genuine (dis)Advantage shafted again

This copy of windows is not genuine

As various sites are picking up, 'Windows Genuine Advantage' is down and helpfully marking legitimate windows installations as counterfeit, including mine.

Last time this happened it affected a large number of PCs at my place of work. I doubt this will be the last time. Turning off features across millions of legitimately licensed computers due to a technical glitch is clearing unacceptable.

Good job I'm only really using windows to play games these days...
