Ubisoft has confirmed its rights management servers were hit by a fierce DDoS
attack over the weekend that left some customers unable to play its games for
much of Sunday.
The attack is an apparent protest at controversial new DRM controls by the
video game publisher which mean customers have to be online in order to play its
latest PC games such as Assassin's Creed II and Silent Hunter 5.
The introduction of so-called Online Services Platform technology last month
means it's impossible to play a game without an internet connection or save
progress while playing a game if an internet connection is lost, as explained in
a interview with Ubisoft by PC Gamer.
