We have determined that the root cause resulting in the server bans is not directly related to Battlefield 3, but rather related to select 3rd party services which server owners can use in conjunction with PunkBuster to protect their servers.

If you are able to log in to Battlelog, your account has not been banned by EA or DICE so there is no need to contact Customer Support.

This issue did not affect Xbox 360 or PlayStation 3 players of Battlefield 3.

UPDATE: As seen in the comments, we are receiving reports that this issue is still affecting some players. We are continuing to investigate what may be causing this issue with some servers.

If you are still experiencing problems please try joining other PunkBuster enabled servers - only a subset of servers are affected.
