The good news is that the developers are aware that this change will affect performance and are hoping to be able to smooth things out over the next two weeks. That’s when the server consolidation is taking place, so that’s all the more reason to hope that all of the kinks are worked out by then. Hopefully your ping rate hasn’t significantly worsened with the move!
Star Wars: The Old Republic servers have had their physical locations merged into one. It turns out all of the game’s servers were moved to a location on the east coast after the game’s most recent maintenance, albeit without any prior notification to players. This has some players (particularly those on the west coast) a bit miffed, seeing as how this will immediately affect ping, latency, and how far you have to drive to manually wipe characters off of your server in a fit of rage.
