Another update seems to be in the works. PageRank and backlinks have updated on the -gv datacenter.
Check it out at www-gv.google.com.
If you want to see if your PR has updated, you'll need to add this line to your hosts file:
(I recommend backing up the hosts file before changing it since a corrupted hosts file will prevent your browser from surfing the web properly.)
The hosts file is located in this folder on Windows XP systems:
You'll need to uncheck the "read-only" attribute for the hosts file before you can add the line.
After you change the hosts file, close all open Internet Explorer windows, go back into IE, then view your pages to see the updated toolbar PageRank for that page (if applicable).
Be sure to remove the new line (or simply # it out) after you have finished checking out your PageRank. I prefer to leave it in mine and just # it out like this:
That way to see the effects of the next update on my PR, all I have to do is remove the # and change the IP address to the updated datacenter.
Also be sure to re-enable the "read-only" attribute for the hosts file.
Here is a list of the Google datacenters and their IP addresses (although it probably isn't up to date):
