Why is wget hanging?

wget to a single specific url from one of my servers keeps getting timeouts. All other urls from this box work fine. This url works OK from any other boxes I have. Here's the output:

wget -T 10 http://www.fcc-fac.ca
--2011-07-14 14:44:29--  http://www.fcc-fac.ca/
Resolving www.fcc-fac.ca... 65.87.238.35, 207.195.108.140

Connecting to www.fcc-fac.ca|207.195.108.140|:80... failed: Connection timed out

Can you tell me what might be wrong and how can I troubleshoot it? I'm using Ubuntu 11.04 (GNU/Linux 2.6.38-8-server x86_64)

Thank you very much in advance and forgive my noobish ignorance :)

ping, telnet, nc www.fcc-fac.ca 80 - all hang. However, some other urls that are easily wget'able though only some of their hosts are pingable.

traceroute doesn't tell me much:

Thanks a lot for answers!

I think that the problem is that wget doesnt handle well IPv6 addresses and the DNS server is sending a IPv6 for that site. Sorry if I misunderstood your question. Check those tests:

hmontoliu@ulises:~$ wget -T10 http://www.fcc-fac.ca
--2011-07-14 16:44:34--  http://www.fcc-fac.ca/
Resolving www.fcc-fac.ca... failed: Connection timed out.
wget: unable to resolve host address `www.fcc-fac.ca'

If I force IPv6 because I believe that your problem is related to it, it fails:

hmontoliu@ulises:~$ wget -6 http://www.fcc-fac.ca
--2011-07-14 16:40:44--  http://www.fcc-fac.ca/
Resolving www.fcc-fac.ca... failed: No address associated with hostname.
wget: unable to resolve host address `www.fcc-fac.ca'

However if I force to use IPv4 it downloads right the index page

hmontoliu@ulises:~$ wget -4 http://www.fcc-fac.ca

Run nc www.fcc-fac.ca 80, type in GET / and press Enter twice.
