Same I was just playing then it told me the servers were down? I thought.. patch? but probably not.
bro this happens so many times to me but its just your net broken try what silent said
me and my whole friend list lost the connection to the servers, too, several times... dafuq happened?!^^
I lost connection about 2100 GMT yesterday mid match and still the same now. The COD status page it says to check says everything is fine, obviously doesn't get updated much.
