I have a couple of pages on my blog that seem to have silently dropped out of google and yahoo. One page used to rank on the front page for the 3 word search term that is the product name that the page talks about. All other pages are seemingly fine, so no big changes for any other pages.
I can see no warnings of 404s or anything else in google webmaster console.

The page is in my sitemap, and has been there since April 2006. The sitemap has 564 URLs submitted. My sitemap is downloaded from google about every 10 days or so - and the has been up there for a year.

cache:URL from google and yahoo returns "Sorry, no content found for this URL" from google and is not found on Yahoo! - but I have definitely seen it in the index for quite a few months last year.

MSN/Live is showing a cached page with a date of 10/04/2007.

Even the seomoz.org crawl test says status code 200 and not cached in google.

Yahoo! SiteExplorer also knows nothing.

I can't see any robots exclusion or anything in the page source. The page is on my private (ISP shared) domain, generated by the new version of blogger. Lots of other pages generated in the same way are happily found with google.

I think it is very unlikely that my ISP returned a bad error code for any extended period.

Can anyone suggest anything else other than just sit and wait (it has been several weeks already).
