We were down for a couple hours this morning -- apparently the upgrade (required due to some vulnerabilities in the prior version of the site admin software) has done something to our RAM usage, and the machine decided to call it quits around 6:30am my time this morning.
We think we've got it figured out, but due to the troubleshooting time, I didn't have the normal amount of time for hint editing and research, so there's only a handful this morning...
