I ask Tuesday and Wednesday 5 persons from 3 different countries of they could reach your website. 2 of them could reach the site and the other 3 not.
Pinging to your domain isn’t successful. I get the error “destination port not reachable” but I get the server IP. So the Name lookup should be OK, maybe it is a problem by your hoster?
I have also tried different DNS servers from http://european.nl.orsn.net/
but they also don’t work.
Via an anonymous site I can reach aardvarktopsitesphp.com.
This site http://www.dnsreport.com/tools/dnsrepor ... tesphp.com
gives a few warnings and errors about the DNS for your site.
Maybe you or sombody else can with this information solve the problem.
