A maintenance notice has been posted.

We will bring the Free Realms PC servers offline on Thursday, June 21, 2012 at 9:00 p.m. PDT (San Diego Time) for a Hotfix to make a few minor improvements. The game servers will be unavailable for about 30 minutes!
Most of the changes in this hotfix will fix Gloam Invasion issues and a crash issue for Mac players.
