Rolling Restarts Wednesday Morning

All US realms will be restarted starting at 5:00 AM PDT Wednesday morning.  The servers should only be offline for about 15 minutes, but you should be prepared for a bit of downtime if you play at that that time of day.  The restarts are required in order to fix what CM Eyonix refers to as a "minor technical issue," though I can't find any further information on what the trouble may be.  I haven't personally seen any problems in playing since today's patch deployment, but perhaps others have.  If anyone has the scoop on what's requiring these restarts, do share in the comments!
