Beginning at approximately 10pm Arizona time and extending until about midnight, all servers will be unavailable while updates are performed. To find the time in your timezone, see here: http://everytimezone.com/#2015-5-7,1020,cn3 The entire server will be unavailable for a short time, and the rest of the maintenance window will see the lobby restarted several times. The maintenance will consist of security updates for the underlying OS and (hopefully) updating the lobby to Minecraft 1.8. And just to be clear, nothing about Hogwarts or anything else in the lobby will be changed, only the version update. Thanks for your patience and understanding.
