All Vanguard servers will be brought down tomorrow morning (7/16) at 5:00 am PDT for a quick patch that contains a few bug fixes, and changed a large number of items that were previously BoP, to BoE. You can read exactly what's going in with the patch over on the Official Forums.
We expect the servers to be up and ready to play by 9:00 am PDT. If they're not, you can expect an update on VGPlayers!
In addition to the server downtime, there will be a period of about four and a half hours where all SOE Official Forums will be unavailable.
The forum maintenance will begin at 6:30 am PDT, and should conclude by 11:00 am PDT. During the downtime, you can visit VGPlayers for any additional updates regarding this maintenance.
So we have the usual 4 hour DT... see you at 6.
