Today I updated my as and now I keep getting disconnected from the black ops 2 server.
If you want someone to help you find a solution, you need to be more descriptive about your issue.
More information would be appreciated.
This is a PlayStation community forum. If it is a PS3 issue, someone here can try to help you with it. (if there is one.)
If it is a game issue (their servers), you may want to contact Treyarch or Activision (since it is their game.)
