Yesterday there have been reports on the official Assassin's Creed II forums about Ubisoft's DRM authentication servers crashing, with players having to endure lengthy login periods when booting up the game. For many people the game just locks entirely.

Ubisoft's rep wrote on the forum that "clearly the extended downtime and lengthy login issues are unacceptable, particularly as I've been told these servers are constantly monitored."

He also said: "I'll do what I can to get more information on what the issue is here first thing tomorrow and push for a resolution and assurance this won't happen in the future."

Oh c'mon Ubisoft. Isn't it about time you went back to the drawing board on this one?
