The team at DICE have announced that the servers will be down for maintenance on Tuesday (8th Feb') 7:00 - 14:00 GMT
for Battlefield: Bad Company 2
Daniel Matros, Battlefield Community Manager at DICE, explains all:
This is the second phase of the stats database rebuild – this phase is done separately for BFBC2 Xbox 360. 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 maintenance will also be happening during Monday - 23:00 - 06:00 PST
and Tuesday - 08:00 - 15:00 CET
The downtimes have also been announced through Facebook, Twitter and the EA UK Forums. Mikael Kalms from the DICE team, has posted a huge description
on the EA Forums explaining what happens with the stats sytem. You could "consider it a peek 'under the hood' of BFBC2."
