Are you using modifications or playing legit?

Sign off, sign back on. Or wait, let it load up to the point BO2 says "service is temporarly down" or in same reference, then just log-in a later time.
Not much you can do, just be patient

i am using modifications

You might be "Mac Address" Banned, as when i was Mac Address banned i had Server issues.

Start the game signed out then once at the menu sign in, wait about 15-20 secs then select online

Loading issues usually occur when your files are corrupt. First, try to follow these steps.

> Turn on PS3
> Load Black Ops 2 While Offline
> When you get to MP Menu press PS Button and Sign in via XMB
> Wait 5 seconds for the lag
> Click Play Online

If that doesn't work, delete your Game Data Utility and reinstall the update.

To get mods to work, do you have to make a backup of the disc? or will it work using the disk. I was looking to use Geo's RTM tool, but every time I load up (signed off), once I get ready to sign on, it shows the Connecting To Multiplayer screen... and it stays there. And when I go to quit the game, it doesn't quit the game it soft restarts my PS3
