Google is playing
These days, Google made us think it will update the Pagerank. Yesterday, 2 datacenters really updated it, especially the new websites, with no pagerank, but he didn`t forget about the old websites either.
Anyway, today everything was back to normal, like nothing happened, it was just a test of update or something like this.
The experts expect the real update to be around the 5th of july, that means in a few days.
