Ubisoft’s DRM servers were overloaded over the weekend, rendering the recently released PC version of Assassin’s Creed II unplayable for many legitamate owners of the game.

In an attempt to combat piracy, Ubisoft announced an extreme method of DRM whereby games required a constant internet connection.

Assassin’s Creed II, released last week, was the one of the first games to support the policy, and its first weekend has been plagued by server issues with posters on the official forums telling of connection outages.

“Due to exceptional demand, we are currently experiencing difficulties with the Online Service Platform,” said an official response on the forums, “This does not affect customers who are currently playing, but customers attempting to start a game may experience difficulty in accessing our servers. We are currently working to resolve this issue and apologize for any inconvenience.”
