WebmasterWorld and DigitalPoint Forums are both reporting significant changes in rankings at Google starting last night. Typically, Google, since December 2003 (aka the Florida update), Google does not want to shake up the search results (did not mention search ads here) before the big holiday season.
Well, these reports seem to be wide and far. So I believe based on the recent volume and breadth that there is a possible Google update underway.
