Here in france, I didn't notice a significant change in people coming from google (april 6th and 7 was slightly above usual, 8 and 9 slightly below).
What I noticed though, is in google webmaster tools : stats for "search queries" are empty for april 6th (says 0, but I received clics from google that day).
And, the last few days, googlebot was crawling much more pages than usual (sometimes, crawling images too from the pages, which is strange).
But maybe it isn't related and is just a glitch.
