Pretty sure the root issue here is with whoever is hosting the DNS for the rattlesnake.com domain:
Query from a machine on a metrocast network:
brks-macbook-pro:~ brk$ nslookup rattlesnakecam.com
Server: 192.168.1.1
Address: 192.168.1.1#53
** server can't find rattlesnakecam.com: SERVFAIL
Query against a DNS server in my colo, from Metrocast:
brks-macbook-pro:~ brk$ nslookup rattlesnakecam.com 66.203.66.203
Server: 66.203.66.203
Address: 66.203.66.203#53
** server can't find rattlesnakecam.com: SERVFAIL
Query directed at the nameserver that is supposed to control that domain name, again from Metrocast network:
brks-macbook-pro:~ brk$ nslookup
www.rattlesnakecam.com NS1.LAKEHOSTSERVICES.NET
Server: NS1.LAKEHOSTSERVICES.NET
Address: 74.54.176.18#53
** server can't find
www.rattlesnakecam.com: REFUSED
Query from one of my colo boxes in Marl, MA:
-sh-3.00$ nslookup
www.rattlesnakecam.com NS1.LAKEHOSTSERVICES.NET
Server: NS1.LAKEHOSTSERVICES.NET
Address: 74.54.176.18#53
** server can't find
www.rattlesnakecam.com: REFUSED
-sh-3.00$ nslookup
www.rattlesnakecam.com
Server: 66.203.66.203
Address: 66.203.66.203#53
** server can't find
www.rattlesnakecam.com: SERVFAIL
-sh-3.00$
