Activision has confirmed that the PS3 version is having server problems, with a large number of users unable to connect to multiplayer matches.
"We are aware of connectivity issues that some players are facing in Black Ops II on PlayStation 3. We are working on resolution, thank you," Activision support tweeted.
On Wednesday (November 14), Activision temporarily took the servers offline to fix connection issues. Though the servers are now online and running again, there are still intermittent reported problems both with users trying to connect to the servers and with getting disconnected from the servers.
On the official Call of Duty forums, Activision confirmed that at one point 100,000 users were dropped at once after the initial fix had been implemented.
In addition to the multiplayer problems, users have also been reporting the game freezing on all systems, though most reports come from the PS3 version.
Activision support suggested that users make sure their drivers are updated if they are experiencing crashing or performance issues; however, that advice is only helpful for the PC version.

Black Ops 2 is available on Xbox 360, PS3 and PC worldwide now, and on Wii U from November 18 in North America and November 30 in Europe.
