I've tried traceroutes, they show that the basic network connection between my home PC and web servers at work is fine.

This is supported by my being able to be logged in to the web server via SSH, actively doing stuff at the very same time my HTTP connections are failing to reach the very same machine (and the others at work, and presumably the others on JANET and the BBC).

It seems to be port specific, that's what's most confusing. traceroute gets through, SSH gets through, ping gets through, HTTP doesn't.

Is there a port-specific version of traceroute? (I don't see how there can be from my rudimentary understanding of how traceroute actually works).
