Today the MySQL database server that runs CAA completely shut down unexpectedly (as opposed to what usually happens, which is "just" it running out of resources). This destroyed a number of critical parts of the database, which was why CAA was acting strangely most of today.
Those portions have been rebuilt successfully and statistics regenerated. So far everything looks fine, so I'm going to open up again.
Please, when reporting technical errors, one or two posts is enough. A large chorus of the same complaint over and over "yeah, me too! yeah, me too!" is very difficult to sort through and doesn't really tell us anything. (Furthermore, the particular thread in question was in Goof Off, and could easily have been missed -- either PM or posting in Comment Box would be much more appropriate.) You can also IM us if we're on for immediate feedback. Any of these methods will help us a great deal more.
PM any odd behaviour (other than the usual slowdowns) to me.
