OP- Not sure if you realize this, but there are people, including myself, who are unable to connect to the Halo 4 servers. I personally have only been experiencing this for 33 hours or so, but others are going on several WEEKS. 343 has not been giving us reasonable updates with what the issue is, or for that matter- a time frame for the fix.
After dropping $80 for the game (including map pass), I think it's fair for us to be more than irritated.
