Google is testing a new data center infrastructure, called BigDaddy, which is much bigger and more comprehensive than an algorithm change. The new BigDaddy data center contains new code for examining and sorting the Web, and once it has been tested fully, will become the default source for Web results. It is supposed to address a variety of issues including 302 redirects and page indexing of only one form of URL that houses similar content (i.e. either www.site.com, site.com, etc).
