Hi,
My website
Search Engine Optimization India PR raised from 4 to 5 because of the PR update from google. last week some of the data centers showed as PR4 and some as PR5 but now it is getting stabilized as PR5 in all the data centres. I think google is having 151 data centres is that right.............
Matt's view about Google PR update
Roughly every 3-4 months we take a snapshot of PageRank values and export them so that the new values are visible in the Google Toolbar. I believe that another set of PageRanks started going out on Friday. New PageRanks are visible at many data centers, but not at every data center. Why not at every data center? Because some data centers are using a slightly older infrastructure for a few query types that are off the beaten path a bit (info:, link:, toolbar PageRank queries, etc)
