At Sat, 30 Nov 2013 14:51:01 GMT, there was a sudden drop in the close votes review queue size from 98932 to 98314. This is about 600 questions over the course of one minute.
It doesn't seem like a routine cleanup script. If it was, this is a very odd time for it to run. Also, the drop occurred over the span of a minute, so it's highly unlikely there was simply increased review activity. So, I ask: What was its cause?
(yes please don't shoot me I know my freehand circle is blue) (it's actually a dark teal look again) (the source for this script I credit to acheong87 (slightly modified), found through the CV meetupthe CV meetup post)
