FWIW, we (retail website) saw a return to some traffic "normalcy" starting on Oct 24th after another drop off (similar to the Oct 13 'minor update') that started on Oct. 19-21. Certainly a roller coaster result the last two weeks.
Down Oct-13th-15, Up Oct 16th. Normal after. Down Oct 21-23 Up Oct. 24. Normal after.
Perhaps the most recent flux (Oct 24-25) was the start of return or meld with Panda iterations to the holiday retail shopping algos?
