I checked the webmaster tools today for our sites and seen the following:
Index status: No pages from your site are currently included in Google's index. Indexing can take time. You may find it helpful to review our information for webmasters and webmaster guidelines.
This is either an error or G is up to something, because a site search for any of the domains in our webmaster tools brings up results, but different results for the last day or so.
On one of the sites the pages G says it has indexed when doing the site: search has gone down dramatically over the last few days while the other site has gone up....beats me what is going on...just thought I would let other webmaster tools users in on what I saw. Anyone else seeing it?
