Ubisoft had warned that a number of its PC games would be unplayable while the publisher transferred servers, thanks to its frightful DRM. The move is underway today, but it seems some games which were supposed to be safe are not working either.
"We apologize for the inconvenience, it seems some of you can't connect to games announced as playable during migration," reads a message on the official Twitter account. "We're on it and will keep you posted here!" added another.
Ubisoft forum members have reported trouble with games including Assassin's Creed Revelations, Driver: San Francisco, and Anno 2070, though Ubisoft is not certain that the latter's woes are due to the migration. If you want to play Anno 2070 but can't, Ubisoft offers a possible workaround.
Ubisoft has estimated that the transition should be complete by Thursday morning. Now, who could have guessed that a DRM solution built upon online authorization could be so fragile?
