DICE says that the PlayStation 3 servers for Battlefield Bad Company 2 will be down at various times tomorrow - February 3rd - tomorrow.

10:00 pm PDT - 3:00 am PDT
0:01 am EST - 5:00 am EST
06:00 GMT - 11:00 GMT
7:00 am CET - 12:00 am CET

This is the second phase of the stats database rebuild – this phase is done separately for BFBC2 PS3. We are measuring performance both before and after this operation. We expect that there will be some minor stats issues right after the downtime when all the players are getting back online at the same time; this effect will diminish over the following 2 hours. The downtimes will be announced on Facebook, Twitter and the official EA UK Forums.
