On Tuesday the 25th of January EA/Dice are going to do a bit of maintenance work on the Xbox 360, Playstation 3 and the PC. The purpose is to improve performance of the stats system, to reduce/eliminate stats outages.
Maintenance Hours:
2:00 am PDT – 5:00 am PDT
5:00 am EST – 8:00 am EST
10:00 GMT – 13:00 GMT
11:00 CET – 14:00 CET
The PC version will take up to 5-6 hours to complete. You can expect that the backend comes up for a few minutes halfway through, and then is shut down again.
Mikael Kalms from DICE posted a great thread on the stats issues on the EA UK forums. Check it out right here.
