I saw some strangeness for awhile this afternoon / evening. From about 4:00 - 7:00 EST, I saw intermittent results that looked like pre-April Panda (at least in my verticals). There were major shifts everywhere I looked.
It will be interesting to see if that was a bug or a sign of big changes to come.
