Ubisoft Entertainment have updated their twitter with word that the problems they've been experiencing (and seem to still be experiencing for that matter) are caused by a hacker who's managed to bring their DRM servers down, making it impossible for people to play new Ubisoft PC games.

An overview of the tweets of the last couple of hours:
Seems hackers are still going at it at full force. Didn't anyone think that people can hack or launch denial of service attacks on servers connected to the internet? And that that might actually mess up the entire scheme of DRM which needs permanent internet connection, even when wanting to play a single player game?

This is going to hurt Ubisoft's PC game sales badly if you ask me. Let's hope they don't decide that they've had enough and quit PC entirely...
