Suspecting IT for blocking certain domains, he complained — and so we investigated. Apparently, the responsible HostGator nameservers ns21.hostgator.com and ns22.hostgator.com selectively refuse to talk to certain netblocks (18.104.22.168 and beyond seem to be good examples). Multiple reports from all over Europe support the idea that this is not an ISP, firewalling or routing issue. Customers with IPs in those ranges are simply out of luck with sites served by these nameservers. We suspected there to be some sort of bogon filtering going on with old data, so we reported the facts and our suspicion to HostGator. After some email exchange, we received the definitive answer that since we are a third party, they would need to have a customer contact them to investigate this issue. So, my questions to the
/. crowd are: Are there any HostGator customers out there who could kindly "contact" their hoster to have this issue resolved? And, have you come across similar instances of failed debogonising?"
