I've been polling for reviews of late answers on SO for about 6 hours now, and the only answers I've got were the test ones. The recent reviews list stays the same for hours and changes by a single answer (and I suspect it's also about the test answers).
The stats for today show a similar story. There are only 2 people who managed to review 4 answers.
Is it incredibly slow day and just a coincidence or is there some kind of a bug in the late answers queue?
