Hold, brethren, these times are sent to test us. Xbox Live is currently being hit by online performance issues, but rest assured that Microsoft is already aware and on the case. At the moment, affected services include "joining other Xbox Live members in online games" and "posting game performance or viewing the performance of other Xbox Live members." Some players may also experience issues whilst playing Grand Theft Auto V and Call of Duty: Ghosts, due to scheduled maintenance work. Blinkbox has also been hit by limited functionality for the same reason. Keep checking Xbox Support's Live Status for more info on when the service will be back up and running. Source Total Xbox
