To begin, all seems to be fine now, but...
The BB was behaving strangely yesterday, went down completely, then came back up, working, but a bit patchy. I couldn't get access to any of the diagnostics on the database or the BB admin panel. Was a bit concerned that we were going to lose stuff.
I had a final go at running a database check, left it for a few hours and came back to find it completed finally, saying ok. The various ok messages were a bit misformatted, and in the midst of them was something about a server restart. Don't know if it really refered to a full reboot of the server, but since then stuff seems to have fully recovered.
To make sure I've updated us from PhpBB3 3.0.2 to 3.0.4, which of course needs to be done anyway. Update seems to have gone fine, but have a look incase anything is astray. The registration mod is still in place but I'm not sure about others.
I love the bomb.
