Just as the latest Google upheaval started, my site's home page disappeared from the search results (it's now to be found at position 700+ on a search where it would previously have been at position 5). At the same time, webmaster tools began to report zero links to the home page ("no links found"), although links to all the other pages are still reported correctly. I guess these two events are connected, although I would be grateful for any interpretations anyone can offer. In particular, of course, will Google reindex those links, and is that likely to restore the site's position? fred9989
I think you'll see that the disappearence of your home page backlinks is a buggy WMT report. Google's Matt Cutts mentioned that the recent new data went live without Google's normal quality checks. GWT problems would be slower to correct than the actual SERPs. Give it a little time.
However, if it doesn't get sorted out soon, you'll probably want to start reading up on the -950 penalty [webmasterworld.com].
