Sorry if this update doesn't include exact times, we've got the beta for the new game client ready and we plan to put this live tomorrow (1pm EST approx). You'll be able to check out the new changes but we're adding a fall back functionality so if you wish you can still play without trying the new graphics engine.
The game will be down for an extended period of time 3~ hours.
We will be taking down all the game servers at 7:00 AM UTC for a quick restart. We expect the down time to last no longer than 5 minutes, after which you may find yourself logged out from the website.
All servers will be coming down in 1 hours time at 5:00 PM (BST) for a brief maintenance restart. We expect the process to take no longer than 10 minutes. Sorry for the inconvenience.
