This update is currently on G*.com, but I suspect it'll propagate to other G* DCs and regional sites very soon. I appreciate if when anyone concurs / seconds my opinion would post here so we can set the re-tweak date as the 28 June 2010!
We are seeing the pattern that we have always seen (pre mayday) which I have always put down to a google monthly dance - 50% drop in traffic on the 25/26th (we had that on top of mayday drop) then return to mayday level on the 27th then today is looking like the numbers are going up, pre-mayday this always happened from 28th to the 5th of the next month. I belive (and predicted a while back) pre-mayday traffic will be restored at the start of July. So yes I concur that something is happening starting 28th but I would say this is 'normal' pre-mayday behaviour (not seen since march for us).
Which ever way you want to look at this, a data restore or a rollback I still belive it can be fully put down to being the first (and perhaps only) caffine dance. This will bring all required data for caffine to function on on all sites into a live dataset then perhaps from then onwards it will be more in real time.
Fingers crossed this is the begining of the end!
