(Can't contact the database server: All servers busy)
AFAIK, it means exactly what it says. I've been seeing it more
and more lately, particularly at around 15:00 UTC weekdays, and
for some reason a whole lot tonight. It may be some strange
database problem, or it may just be evergrowing load outstripping
server capacity again..
