I think the *.archive.ubuntu.com geo-dns thing is completely broken


traceroute to (, 30 hops max, 60 byte packets

So the first IP for au.archive.ubuntu.com is pointing to a UK server!
Note: this depends on the behaviour of wget or apt-methods/http.
Yesterday I was routed to a US server for that hostname. I wish I knew
who to contact for that.

Your best bets (at least IMO) for Debian and Ubuntu
* debian.anu.edu.au (good job iiBorg, you've routed this through Melbourne)
* mirror.optus.net (straight to Sydney)
* uberglobalmirror.com
* mirror.linux.org.au (when it's back).

I thought congestion was my issue now, but I see that it's silly
routing by TPG. For a laugh, if you've got a friend on TPG ADSL or NBN
in Canberra, get them to traceroute your iiNet/Internode IP address -
when I tested this it went around Australia and back instead of just
going through Canberra.

If anyone has contacts at TPG or what remains of iiNode, can you find
out what they're doing with their routing?
