Nothing is working on the server at the moment. Assuming logins work, expect there to be rollbacks to the nearest snapshot to 9:00pm PST. You may lose progress. This is due to players still being able to place and destroy blocks, if they are still logged in from when the server crashed. Whether or not any progress is even logged is unknown. When Zerg comes online, he will be able to make a decision.
Until then, keep calm, and put the kettle on.
Be patient. It will be back up soon enough. Sorry for any inconvenience.
