Here's the same notice I posted on SP:
"We've had about 7 hours of downtime today, and I'm afraid there will be more. There are certain issues with the server's hard drive file system which are majorly messing around with things, and I'll need to run some lengthy diagnostics and repairs to hopefully fix it. The server and all sites on it will be inaccessible during this time. Sorry for the inconvenience, I'll get everything back up as soon as possible."
