Problem Solved, it was their fault. i knew it.
After waiting a month, we finally can access the online parts of the game. To be honest, the game wasnt good on multiplayer.

Its no backup issue at all....
I have Backup & disc version now...
On my jailbroken console I got the issue yesterday was dreading to see it thought I was banned.
Got on my retail and made a new account so it was bulletprood played 10 minutes and got the same damn message.
Its the servers their shit as always and tryarch know's there is a problem their not addressing it because they know if they claim their servers already fucked before the release their fucked themselve's.

Im sure The ones who are Playing on the Server are the devs Anyone Else cant Access it until Official Release, there will be an Update 1.03 before the Server opens gates.
I also think that theres a Problem with the Recent Update 1.02 Causing the freezes and disconnects

I've tried Several versions all with the Same issue, maybe its Region specific

Nope has not worked since I have got it still trying it after every campaign mission.

Maybe wait till the actual release date? Im not sure, sounds really annoying too. Hope this doesnt happen especially when I get it on Tuesday.

This issue is NOT because of the servers, that is one thing I am sure of. I believe it's pretty accurate to say that Treyarch are issuing some form of block or ban because I was able to get on BO2 Multiplayer, played 1 game and then have suffered server unavailable every attempt, but then switched accounts and I was allowed on, again for 1 game, but now that account cannot get on either.
