Hi there, I'm not quite sure about is this google still updating or not. I see that my PR has not been updated yet in all DC's but my site ranking down from #17 to not top 100 in 1/3 of Google DC's. Is this involved with Google update?? I'm not do anything harmful except update contents and links, if my site ranking down, I don't understand why?? help me. Regards, Sxperm
Google is installing an infrastructure upgrade across their data centers. Not all are done and it will be a month or two while this happens. Only the data centers with the upgrade reflect the new public Page Ranks and the other data centers will reflect the same as they are upgraded.

How come the datacenter results all match each other, but I see different results in my live searches? Is there a delay for the datacenter results to propagate or something?
