I am getting this message when I open my webmaster toll dashboard "Google couldn't access your site because of a DNS error". I have confirmed it from my host and there is nothing wrong with their DNS. Is there something wrong with google or what? I tried to fetch as google and it failed. Please tell me what should I do to get it fixed? What impact will it have on my site or SEO if I ignore it completely?
I think something is seriously went wrong ! Well did you re add your website in Google Webmaster tool. I understand "Moving to new host won't solve my problem in any way." But Re-Adding website in Webmaster tool may be helpful & you can short out this Big issue.
Oh Wow Congratulations for it but how did it solved automatically ! Do you think it was solved for any other reason.
what you can do is change the dns name server and try to reset and back to what it should be now. I faced this problem when hosting with Webhostingpad and the uptime is terrible. After i reset the dns field and got it propageted 100% correct this time, it works and the site is back online 99.9%
It's nothing to worry about it happens frequently. If Google tries to crawl your site and your server is down or has a hiccup or G can't access your site for any reason you get that sort generic error message. There is no such thing as a server that is up and accessible 100% of the time so you will see this from time to time. Just delete the message and relax.
My own less know the cause of the problem you are experiencing website. But perhaps it is the effect of google updates.
