I'm getting the same problem. Just went to do a system update, which apparently i needed to do (although it didn't pop up with the usual "a system software update is required". Did this, gone back in to COD and it is still giving the same message about servers being down...
There is something on here stating "All Call of Duty: Black Ops services are online, but due to recent server updates, status has been downgraded as a safety precaution. Users may experience unexpected disconnects as maintenance is conducted. This maintenance is scheduled to conclude by end of day February 22nd, 2011."
