Broadband company intercepting a non-existent website.

A Full Journey

Having confirmed that your local DNS server is working, you can tentatively try to establish human-friendly contact with the Internet using traceroute with a domain name instead of an IP address, and leaving out the -n option. The command is tracert on Windows. This will report a readable name for each router.

$ traceroute -q 1 www.smashingmagazine.com traceroute to www.smashingmagazine.com (80.72.139.101), 30 hops max, 60 byte packets 1 * 2 brig-core-2b-ae6-725.network.virginmedia.net (80.3.65.177) 10.542 ms 3 popl-bb-1b-ae14-0.network.virginmedia.net (213.105.159.157) 13.934 ms 4 popl-bb-1c-ae1-0.network.virginmedia.net (213.105.159.190) 14.454 ms 5 nrth-bb-1c-ae7-0.network.virginmedia.net (62.253.174.137) 15.982 ms 6 nrth-tmr-1-ae1-0.network.virginmedia.net (213.105.159.30) 16.215 ms 7 fran-ic-1-as0-0.network.virginmedia.net (62.253.185.81) 36.090 ms 8 FFMGW4.arcor-ip.net (80.81.193.117) 39.064 ms 9 92.79.213.133 (92.79.213.133) 47.404 ms 10 92.79.200.190 (92.79.200.190) 45.385 ms 11 kar-145-254-15-178.arcor-ip.net (145.254.15.178) 40.421 ms 12 145.253.159.106 (145.253.159.106) 46.436 ms 13 1-3-frr02.continum.net (80.72.130.170) 49.321 ms 14 1-6-frr04.continum.net (80.72.130.158) 47.194 ms 15 www.smashingmagazine.com (80.72.139.101) 48.081 ms

This reveals much more about the journey packets of data take. After it leaves your local network, the first few hops in any traceroute are probably owned by the local broadband company, Virgin Media in this case. If the traceroute stopped here, then it would be an issue for them resolve. You could phone them for more information.

Once the traceroute leaves your broadband provider, it enters a no man’s land of big inscrutable networking devices. In this case they are owned by Arcor, a subsidiary of Vodafone. If the traceroute fails here, it may represent a fairly major networking problem and there’s not much you can do.

Eventually, it will reach the hosting company for the website in question (Continum.net in this case). If it fails there, then the fault may lie with your hosting company. Or it may simply be that the traceroute is blocked by a firewall. Or that your website has moved.
