[Halo 4 matchmaking servers currently unavailable]

This is the first time I have had any issues and it's been going on all day. I didn't change anything. I just started playing today and it was like this. Does anybody know anything about what is happening to me?

I am currently having the same issue. It started at about 10:00 this morning and continued throughout the day. It is telling me that there are only 500 people in Infinity slayer and less in the other playlists. I can join games and play but everyone i run into is terrible and there is never a game full of people. I can't join up with any of my friends either. It says status joinable under their profile but when I try to join it doesn't work.

 

How do i contact 323 about this problem?

 

Please Help! this is very annoying!
