I was working on some last minute preparation work for tomorrows upgrade, and slipped. This caused the empeg boards database to be dropped, with my last backup 2 hours old.
And yes, once I got it back up, the same "slip" occured again. After talking about the phpMyAdmin slipup, wfaulk volunteered in IRC to do the merger all by hand at the mysql> prompt. :-P
Thus, posts made between 16:24 CST and 18:20 CST were lost. The server had ASCII logging on, but not binary. So, there was no easy way to recover them. Binary logging is now on to prevent this sort of mishap in the future.
