Now is the absolute worst time for Xbox Live to be down. Tuesday marked the debut of Titanfall, the game that could make or break the Xbox One game console. It's a masterpiece of mechanical manslaughter, and Microsoft pulled out all the stops for its release, delivering new system updates, new peripherals and even a "fix" for the Xbox One game controller ahead of its launch on Tuesday. But now, as prospective US players return home from work to play the Xbox One's killer app, many are finding themselves unable to sign into their consoles and actually play the game. With some games, that might not be a gigantic problem. You could simply play a single-player mode. But Titanfall is a multiplayer-only game that's joined at the hip to Xbox Live, dependant on the service for everything from dedicated servers to AI calculations. You can't even play the tutorial without a connection.
A later update said the situation was fixed: "The official Xbox Support Twitter account claims that Xbox Live is "good to go," though the status page still lists service as "limited."
