Fetch as Googlebot – Failed

If fetch as Googlebot has failed due to ‘Unreachable’ then note : Unreachable means literally that Googlebot cannot reach a site. Other user agents may be able to access without problem and you may also see your site render fine in all browsers.

For your site to remain indexed, you need to ensure Googlebot can crawl your pages.

Troubleshooting

Other fetch as googlebot failure reasons include DNS errors and time outs. Again, these would be issues which would need to be solved locally and ideally with the help of a knowledgeable host.
