It is some sort of automatic "circuit breaker" that kicks in where there
are an abnormal number of queries (usually, I think, unauthenticated
queries, but it might not matter) coming from a particular IP or
"browser fingerprint".  I haven't a clue the particulars, but I've
tripped it a few times before.  Not in some time, though.
