It seems that a Google PageRank update is imminent.
To check what the Google Data Centers are saying about your PageRank use Future Pagerank, a tool that will query Google's various data centers to check for any changes in PageRank values for a given URL.
Some data centers, like 216.239.53.99 and 216.239.53.104, will show different values if your PageRank has changed. You will basically see two values: one is the current PageRank and the second one the new PageRank.
You can see in this screenshot that Xooglers, the blog created by two former Google employees (ex-googlers), increased their PageRank from zero to 7 in just 3 months. Xooglers has more than 1,570 links and many are from high-ranked sites like Digg.
