Can any one tell me why Googlebot cant fetch my website and its links? I have a website and for past 30 days Google Webmasters can't fetch any links from my website. This caused the removal of my website from Google search. I also tried "fetch as Googlebot" option but it failed. The error it's showing is "DNS issue-Links unreachable and Time out error". I also have Google Analytics and Bing Webmasters Tools accounts which work fine (Bing crawls and fetches links from my website). I can access my website through browsers also. I have searched other forums and found out that it may be my hosting providers blocking Googlebot. When I wrote to them they told me that they have allowed Googlebot to my website.
Now I have become a little frustrated about this problem. I really don't know why this error is occurring. I cant even add Google AdSense because of this problem. If anyone has or had this kind of error can they suggest what causing it?
