Same issue here. I'm on PC trying to play AC Revelations Multiplayer but I keep getting a message that I'm in offline mode. I checked and double checked and I'm not in offline mode. I don't know what's going on!
Still unable to connect to AC3, "The Ubisoft services are not available". . . Boys play AC3 Multiplayer and the last several days have received tis message when they try to play. Whats up?
On AC4: Black Flag, I've been trying to access Kenway's Fleet, and I keep getting the "server is not available at this time" message as well. Now I won't be able to finish the game with a 100% completion score.
I have the same problems as Anti 360.4-Life. It was working fine two weeks ago but now i can't access leaderboards (in SP, MP is working), shared event and Kenway's fleet.
