Whoops, I did it again. The 1/2 hour downtime wallago was due to user error this time.
I didn't think to check over the mysql config file since moving the site over. The settings were for a review I did early last year and resulted in bin log files filling up the partition. So, things just kinda ground to a halt.
Sorry about that. We might encounter other little glitches in the near future, but hopefully I'll notice them before the site's been down for 20 minutes.
