Well, as you might notice, several comments are now missing from yesterday's news post. This is because the server just crashed, and I had to restore from yesterday's backup.
Unfortunately I still don't completely know why it crashed. I have it narrowed down to a pretty specific area, but it'll take careful examination of the code to find out what exactly happened and fix it.
The good news is that the server ran for over a week without a hitch before that. And that was on my first attempt at real-world usage, so that's pretty damn good, IMO. Clearly the crash bug that occurred is very rare, so it probably won't happen again before I manage to find and fix it.
More good news is that restoring from backups works flawlessly. I've been rather uneasy about that whole system since it's very complicated, but this was by far its toughest test yet, and it had no problem. So, yay.
