The Ubisoft Forums has a post about a user unable to play Driver: San Francisco because the driving action sequel was unable to authenticate itself over the internet. This seems to be a result of the recently announced server move, which was not supposed to impact this game, as Eurogamer notes a Ubisoft tweet saying: "We apologize for the inconvenience, it seems some of you can't connect to games announced as playable during migration." They also say users have been having trouble accessing Anno 2070, which was also supposed to be playable during this transition. There may be a simple explanation for this, however, as the original forum post was edited when the posted discovered he could play Driver: San Francisco by using the provided "offline mode" option, though he does defend his oversight saying the large banner saying: "Ubisoft services are unavailable at the moment. Please try again later." There's no indication in the thread about Anno 2070 downtime that this workaround is available in that game.
