Change in the display of Google results - Google Pluto update?

We’ve been noticing that Google does not return the usual domain information, when we search for just the domain name. The buzz about Back Link Update is getting public attention, as reported. A Webmaster world thread reports that back links are being updated at some of Google's data centers. This has been happening since the reported Google Pluto update of 24th August 06 - a back link update, with no significant changes in the SERPs.
