Update: We currently anticipate that beta realms will be available by approximately 7:00 p.m. PDT.

We're currently in the process of bringing all beta realms offline for maintenance. We don't have an ETA at this time for when maintenance will conclude, but we'll provide updates (in this thread) as they become available.

Thank you!
