I didn't see anything move on mine in datacenter checks... however...today I did see two of my sites show little blips that I've not seen before. My currently PR5 page showed PR1, and my current PR3 page showed a PR8. What is odd is that my cache, history, cookies, etc were all cleared when I pulled up these pages...so they weren't like left over from my last page I had up. But then the
pr disappeared completely back to PR0 on both sites. And then later in the day it went back to the 5 and 3 it has been at for the past few months.
Weird.
