Due to the need for emergency maintenance on the Santa cluster (where am I?), journals hosted on that cluster will appear to be missing for approximately an hour, and users may receive a database error while attempting to log in. We'll have the maintenance done as quickly as possible. I'll update here when finished.
If you're on that cluster some of your comments are posting blank. Chances are you got an error when trying to post, but a blank message showed up anyway. This is a bug. The problem will go away after that cluster is back up (though the comments will not show up on their own).
