Ubisoft Apologizes For Far Cry 3 Server Issues
 

Ubisoft is apologizing for the server issues preventing people from playing the PC version of Far Cry 3. The quick workaround is to play in offline mode but this is still a huge mess. We're very sorry for the server issues affecting Far Cry 3 on PC and are working as fast as possible to restore the service.
