Thanks Adrian. Just a couple of things though. I'm presuming it's a Squid related problem as all the problems disappear when I bypass Squid from the browser. The path remains the same though as the box running Squid also does ip masq/NAT type stuff as well, acting as the default gateway for the network. I'm also seeing various slow connections appearing on other sites, and while Squid has always slowed our browsing down, it's never been like this before.
Also, when you suggest tracing the 'tcp state engine,' what are you referring to? I'm not a Squid or TCP/IP (or anything really) expert though I'll happily trawl through packet traces, I don't have the depth of knowledge to necessarily work out what's an unimportant error and what's a sign of Squid going the way of tasty marine life.

If you see differences at the TCP layer for just one page then I would be worried. :) Ok, so if -everything- to the wiki server is failing for you I'd grab out wireshark and some paper/pencils and start tracing the TCP state engine. You may find that some device (firewall, router?) is unhappy with something - eg the order of TCP options (which just bit FreeBSD-7 in their TCP code reshuffle..) - and you'll want to compare the TCP establishment dump from this to a known working setup to see whats different. adrian
