Yep, haven't been able to open this site anywhere in Australia for 6+ months now.
Even when using 4.2.2.1 and 4.2.2.2 as DNS servers (U.S. based) it doesn't work, though I dont have trouble resolving the IP, so I am guessing it is blocked outside certain areas.
The name servers are ns3.planetnoc.net and ns4.planetnoc.net
Here is a traceroute from a U.S. based site
