Ran into a problem with the servers. Help

Alright, so I’ve been playing Halo 4 for a while now. Overall, I’ve been enjoying it. I made it to SR-34, have the deadeye helmet and such. My problem though, is that for the past two days, when I go to play matchmaking it says:

“Cannot connect to the Halo 4 servers, showing only the default playlist”

These default playlists only have like 80 people in them at the most. Playlists like regicide are lucky to even have one person in them. Not only that, but on my player card it shows a default recruit spartan with the default emblem and default pose. It also says that I’m only SR-1. I tried coming onto this site and see if everything still loads here, but I cannot even see my stats or anything here. Nothing loads and it’s bothering me.

Also, my brother hops on and although the playlists still give him an issue, his armor, emblem, stance, and rank load just fine.
