There are those who like to watch the Google data center fluctuate and those who prefer to wait until a data center moves over to the main Google results. If you are one of those very detailed people, who enjoy watching each and every data center shuffle, then there is a thread for you at WebmasterWorld. Reseller posted a new thread named Google Datacenters Watch.
Some people in the thread discuss the various data centers, specifically watching http://184.108.40.206/ where big daddy resides. And some people are getting sick of the watch.
Either way, if you skim through the thread, you may pick up a few tid bits, or you may not.
