Are you getting struggled from the Temporarily unreachable error into your Google Webmaster Tools – Search Console?
It’s unbelievable that if you google this problem you will only find the obvious: “don’t worry, it’s a temporary problem”, or “your site is penalized”
Well, in my case, everything that I found on the web didn’t fit with my situation.
New domain, new server, and since I used CloudFlare to cache everything I was worried that the problem was really CloudFlare itself.
I checked everything: DNS, Server Connection, Routing issues, etc. – without any luck.
