What is wrong with the Call of Duty servers on Xbox 360?

I feel like breaking my disk right now. Ive been playing today and every time my team is on top or im doing good, the game disconnects and all I see is a stupid message that says "lost connection to host" or something like that. For instance i had a game where i was 28-8 and I got disconnected and earlier i was 4 kills from a ******* KEM STRIKE 21-0 and I got disconnected.

Ive seen on youtube that people can crash games by using a certain class, but you'd think that the dumb ***** at infinity ward would have fixed that by now. Do you guys have any insight on why this is happening or how I could fix it?
