Ubuntu fails to select the closest mirror

I have installed Ubuntu 12.10 Quantal Quetzal (server edition).

While installing it, it asked me about my location I'm in Bolivia, so the mirror chosen for me was bo.archive.ubuntu.com which is actually an alias of a server in Brasil.

nslookup bo.archive.ubuntu.com

The output was:

Server:		8.8.8.8
Address:	8.8.8.8#53

Non-authoritative answer:
bo.archive.ubuntu.com	canonical name = ubuntu.c3sl.ufpr.br.
Name:	ubuntu.c3sl.ufpr.br
Address: 200.236.31.4

And if we do a traceroute

traceroute bo.archive.ubuntu.com

The output is:

We can see, that the request had to travel from Bolivia, to US (Florida) and then go back to Brasil, and then the traffic from Brasil to US and to Bolivia.

Brasil is maybe the closest server to Bolivia, geographically talking, but not from the network point of view.

It would have been better to choose a US server, one in Florida would be great. I always change this by hand when I finish installing Ubuntu.

But it should works automatically, this way we are only adding traffic to networks. And someone is paying for that traffic.

Also the reply has more delay, and more possibilities to be saturated in any of the ways.

I think Ubuntu should try to solve this, and I'm sure is the same thing if you are in Africa, lots of Africa's countries, connect directly to Europe, while not interconnecting between them. The same is true in South America. All of us go to U.S. not too much interconnection between us.
