I've got a ticket open internally about this; we would appreciate
traceroutes and so forth - lets take that offlist - if you reply just
to me I'll forward it to the sysadmins looking into the issue (and
keep in the loop myself).

I guess initially we need:
 - tcptraceroute on port 22 to bazaar.launchpad.net (has address 91.189.90.11)
 - tcptraceroute on port 443 to launchpad.net (on addresses
91.189.89.222, 91.189.89.223)
 - mtr bazaar.launchpad.net --report-cycles=15
 - mtr launchpad.net --report-cycles=15

And anything else that you think might be interesting to start with.

We have a VPN we can try as well, which can be useful to rule out
various routing policies in the intervening route.

Thanks in advance,
Rob
