Is "dp blueberry" some kind of specialist activity that only consenting adults with unusual kinks should be involved in?
I reckon they planned on a staged launch, have a staged rollout of servers planned to go with it, and are instead receiving massive influx of VPN-cheaty-cunning-types that's spazzing everything up a bit. If that's the case, they probably WILL wait until the 7th before assessing everything. Assuming it's capacity at their end that's the problem (possibly in the server-battlelog interface) I can't think there's a huge amount they can od about it before then anyway.
