A quick query to Craig "Grimwell" Dalrymple, SOE Senior Community Relations Manager, told us that this maintenence will affect all SOE games.

Beginning at 4:00 AM PST on Tuesday, February 17th, all log-in servers will be undergoing maintenance. During this maintenance you will be unable to log-in to all games and account management tools, and you will be disconnected from the server if you are already logged in. We expect this maintenance to take approximately 30 minutes.

Also on Tuesday, February 17th, from 6:00-8:00 AM PST, SOE Account and Commerce flow, the Station Store, will be unavailable due to maintenance. We expect this maintenance to take approximately 2 hours.

This maintenance session will prevent log-ins, but players who are in-game should stay in game until they zone or otherwise make a request from the session system. 

This might also cause some forum accounts to temporarily lose permissions, due to the inability to verify account status while the maintenance is taking place. This is only temporary and normal permissions will return automatically once the maintenance is complete. 

We apologize for these interruptions and will resume all affected services as soon as the maintenance is completed.
