“Multiplayer is Unavailable. Please Try Again Later”

Hello hello. I’m trying to okay some online multiplayer. My internet and other games are working fine except infinite. Is this the infinite servers define for everyone, or is it just buggy for some people sometimes?
Thanks.

Well I got into an Attrition game, but can’t get into Tactical Slayer. Weird.

When does it fail to get you into a game? I was unable to find games last night as it would fail over and over again at 0% loading map.
