Servers have been up and down all night on the Xbox 360 version of Battlefield 3.
The game launched in North America yesterday, but despite a beta test which publisher EA says was downloaded 9.5 million times on all platforms, it appears players have been struggling to get into multiplayer games.
Despite the offical Battlefield Twitter account declaring the problems resolved six hours ago, gamers continue to report problems on Twitter and forums. Some users are also struggling with the Battlelog service.
The most recent official update says maintenance is ongoing, and that servers should be back online shortly. Battlefield 3 will be released in Europe for Xbox 360, PC and PlayStation 3 on Friday.
