I received this message from Google Webmaster Tools:
Over the last 24 hours, Googlebot encountered 2 errors while attempting to retrieve DNS information for your site. The overall error rate for DNS queries for your site is 40.0%. You can see more details about these errors in Webmaster Tools. Recommended action
I've contacted HostPapa and they deny that there is any issue with the site / server. Support from them in terms of what I can do to actually resolve this issue is non-existent.
The site is currently online. I don't know much about DNS, so any advice about what I can do to resolve this problem would be much appreciated.
Basically, the message from Google says that it is my webhost's fault, the message from my webhost (HostPapa) is... "Just tell Google to crawl your site as there are no errors."
