Disconnected From XBLive When I Try To Play

I’ve been trying to play online for the past 30 minutes but I keep getting disconnected every time I try to find a game, or even load up Halo 4! I test my connection and it connects just fine, but whenever I load up this game, sometimes even just at the main menu, I get disconnected. What’s going on?

Maybe that the new playlists are being added. Are any of your other freinds having the same problem?
