I have submitted my site map to both yahoo and google, they are both downloading them everyday. Google downloads sitemap_index.xml.gz, and then sitemap_1.xml.gz, sitemap_2.xml.gz etc. It appears that Yahoo only downloads sitemap_index.xml.gz and never gets the other ones at least according to the download logs.

I have 40,000+ pages with google and yahoo only shows 8,000. What am I missing?

Thanks,
