Today I checked my site and noticed that home page has been switched to old cached data from July and all other pages gone to supplementary. Hope that Google hasn't a temperature.
Take a look here: http://forums.digitalpoint.com/showthread.php?t=153887 Google is doing a update and sites/pages appear to be going supplemental including a bunch of MSN and Googles own page. Just wait for it to all end and your pages should go normal. Just read my article at the above post.
