Looks like this activity was all early this morning, like maybe there was a different data set, but by the time I got up and started checking it was back to normal.
I noticed pretty much the same thing this morning. Traffic was stronger than I anticipated after being decimated by the latest Google updates so I started poking around. Things seemed to settle back down after a while unfortunately.
