Main server is back up, and everything on the main server (only the main server, classic, wastelands, and games are unaffected) has been restored to a point a few hours before the problem first occurred.
This means there has been a rollback of everything that happened after midnight last night, Central time, on the main server only.
We'll be monitoring things very closely to make sure everything is running properly again.
Thanks for being patient while we worked to get a pretty serious situation resolved.
