For those who like to know these things: our crash was caused by a fault in the UPS (uninterruptible power supply), a device meant to ensure the server doesn't crash in the event of a power outage. Ah, irony.
The server crashed yesterday, ushering in a dark, dim period where nobody could access their nations. People experienced a wide variety of problems, including being told that their browser was not sending cookies and receiving a lot of "Could not connect" errors. But we're back up and running now! Investigations into the cause are underway.
Work continues on building a web interface for moderators to review and edit player-submitted issues into a form suitable for use in the game. There are close to 2,000 of these waiting for processing at the moment! Hopefully we'll start to process them in bulk within the next couple of weeks. Thanks for your submissions -- and your patience!
