i see google updates pr in the end of month. But in october, i didn't see it. maybe in this end of november
It looks like a "New site" update. Established domains don't look like they're changing, but new domains and new posts are starting to get some initial PR (mostly 0s and 1s.) At least, that's what I think is happening. 95% of my pages are unchanged, but I've definitely seen some 0s on newer posts that had been N/A before.
I had a PR5 blog 5 days ago, now its PR is N/A. I don't know whether Google PR is updating or not. Some sub-pages still keep their pagerank, one of them is PR5. Who know why?
All the datacenters are currently down so its either they are doing a PR update or someone pressed the switch of button by mistake
Hmm okay. Can someone tell me how to check if datacenters are down? I'm usually caught unaware and then I'd be panicking when my sites suddenly go over the 100th mark.
