They seem to be shifting between two or more result sets. Sites appear and disappear in masses. Including PR10 sites like google.com have had no cache. They then reappear suddenly. When google.com has no cache my site has cache from march 24 2004. When the high PR sites reappear my cache date is normal. I have seen this twice today.
