I went on Activision Support site and found this.
UPDATE (11/18/12): A patch has been released to fix the lock-up/freeze issues affecting Call of Duty: Black Ops II online gameplay on PlayStation 3. However, we are aware that some customers are still experiencing PS3 lock-ups after installing the patch and we are doing everything we can to get to the bottom of it as quickly as possible.
Anyone get a patch today? I didnt. If you did, did it help you at all?
Nope, no patch for me either. It might release sometime today, though.
I get the error message that servers are down. ONly thing 1.03 update did was stop the frezing of the treyarch symbol. FIX THIS SH*T TREYARCH!
