Dear 343i,
Last night (11/20/2014) I was always able to get into games successfully. I would disconnect from a game here and there, but I was getting into lobbies, and games. As of this morning (11/21/2014) when I try to connect to a multiplayer game the following happens: Searching For Players, Players Found, Connecting to Session, (then one of two) Connection Failed Could Not Connect To Host, or Connection Failed The Session is Full. Until MP is fixed I’m going to get back to getting what I can of the 450 achievement related to single player.
