Established internal page dropped from google index

can one google bomb oneself by using too many sitewide links

I recently revamped an old internal webpage that was in google's cache. I also created some new links from the website's sitewide header section to point to the newly touched up page outlining some new services.

The page now has zero PR and is not in the cache.
We dont over optimize, if anything we made sure the page was clear of copy content by using copyscape.

The site maintains its ranking generally, just this page has disappeared from google's radar without a trace. it didnt even go into supplemental! What's even stranger is that the pages subpages are cached?

Has anyone seen anything like this before?

When I see something like this I suspect a technical error - either Google's or mine. Have you validated the page for a major html error that might cause trouble for the spider?

I think Google launched a filter on internal linking about 2 weeks ago. A lot of site wide linked internal pages have dropped even ones that have external links to them. Not sure how to fix them.
