For some reason I can't access anything on python.org. nslookup resolves the IP address, but no browser or curl command will fetch anything. It works fine on a VMWare Ubuntu virtual machine and on a Windows machine on the same network. I've checked there's nothing funny in /etc/hosts

I don't know where else to go looking for issues, can anyone suggest anything?

Running OS X 10.5 Leopard

Do all other sites work okay, e.g. www.google.com ? –  JBRWilkinson Apr 23 '10 at 11:21
    
Have you tried other browsers on OS X? Firefox, Chrome? –  Doug Harris Apr 23 '10 at 13:15
    
@Doug "no browser or curl command will fetch anything" - so yes –  Rory Fitzpatrick Apr 23 '10 at 14:14
    
@JBRWilkinson yes, everything apart from python.org (and it's subdomains) –  Rory Fitzpatrick Apr 23 '10 at 14:14
    
whoops, missed that part. –  Doug Harris Apr 23 '10 at 14:28

Do you have IPv6 enabled for your network connection?

This may be related to python.org having an IPv6 address configured:

$ host python.org
python.org has address 82.94.164.162
python.org has IPv6 address 2001:888:2000:d::a2
python.org mail is handled by 50 mail.python.org.

Googling for "ipv6 python.org" brings up some interesting results such as this Chromium bug report. The comments indicate that a bug in OS X has been identified and that the bug still exists in Snow Leopard.

Try disabling IPv6 and see if it helps.

Look if Parental Controls are on for that users' account - it works by proxying via a local daemon which has an heuristics-based filter would could be mistaking 'python' for a censored term.

I enabled Parental Controls for another account on my mac and had no trouble accessing python.org in Safari. –  Doug Harris Apr 23 '10 at 13:41
    
What would be behaviour be if this were the case? Currently it just times out trying to connect (after a long period of time for some apps) –  Rory Fitzpatrick Apr 23 '10 at 14:15
