Update: This situation has been resolved. We have restored the service without needing any rollbacks and everything is operational again. Once again we apologise for the unexpected unavailability period.
Our game servers are temporarily inaccessible right now. This outage is unplanned, but we hope to restore service soon. We expect resolution today so don't panic.
Update #1: ETA to resolution is about 12 hours from now. (It's 10:34 UTC now)
The problem is a faulty storage controller, and those are always lots of fun. The good news is we're able to recover the live data, which means no rollbacks, the bad news is that this is a slower process than reverting to yesterday's backups. So nobody loses anything except playing time, but we're going to be offline a bit longer than expected.
Apologies for the inconvenience!
