If you're seeing the same thing, I'm guessing that something in london
that would be hop 6 doesn't have a route to either all of occaid or mit.
But the traceroute from packages.debian.org suggests otherwise.
Are you able to get to www.netbsd.org, just as another data point?

Do you have access to your subnet's router? Can you started up route6d
(if BSD, or the Linux equivalent)? Here are the routes I see in the MIT

There are probably some static routes on limekiller, too.
