Holy wow, what happened here?

I was looking at Charley’s visitor stats and noticed that last month my average was nearly 19,000 independent visits a day. My usual average is 9-10,000 visits a day. When I looked at the page for April at first I thought there was a mistake, because most of the days seemed to hover around 10,000, sometimes more, sometimes less.

Then I saw April 21 and 22. 30,509 visits for April 21. And a whopping 198,839 visits for April 22.

Whaaaat?

The number of visits for the days after that are elevated, but not hugely so — around 15,000. And surprisingly, the most-visited casefile is not Peter Kema‘s, but Tammy Leppert‘s.

Did something big happen in Tammy’s case that I’m missing? The only thing I can find is that Tammy was the subject of this Reddit thread.
