It looks like Google is doing another round of PageRank updates. A check of my blog at Live PageRank shows I’m doubling my PageRank from a PR2 to PR4. Right now 21 data center has me at the new PageRank.
This is lower than the PR5 that the Google PageRank Prediction tool (below) predicted but that’s better than staying at the same PR, or worst, dropping! Feel free to use the tool to see if it can correctly predict your new PageRank. After you get an answer, head over to Live PageRank to find out what your new PageRank really is.
