Authority site in competitive vertical which attracts a LOT of link spam. Originally hit with version 1, no change in version 2. Submitted a large disavow file to deal with the link spam around 6 weeks ago. With this latest update, saw a 10% hit for approx 48 hours and then the traffic snapped back, almost like a switch was turned back on.
I'm assuming it's something to do with the disavow file being processed. Just not sure yet if the drop or the recovery was a result of the disavow.
Has anyone else seen such strong bounce back from a penguin update before?
