Here are the 2 sets of cables involved b/w NZ, US and Japan:
https://en.wikipedia.org/wiki/Australia%E2%80%93Japan_Cable
https://en.wikipedia.org/wiki/Southern_Cross_Cable

Maybe we should ask the NSA to remove their MitM boxes... ;)

I will try to see if overriding the mirror helps.

Right now, the MaintenaceTool is downloading at less than 10KiB/s!?!
and sometimes get stalled...
Then i did a google speed test in parallel of the MaintenaceTool and I
got 5 MiB/s (mega-bytes) both way to/from Google's Auckland servers.
So my end point (Auckland office) is not the bottle-neck.

A speed test with
- DigitalOcean San Franciso gives me 3.59 Mbps (mega-bits)
- DigitalOcean New York: 4.56 Mbps
- DigitalOcean Singapour: 5.88 Mbps
- Australia: 18.66 Mbps
- Taiwan: .. stuck...
- Japan: .. stuck... oh wait! na, stuck again
- NZ DSL: 61.08 Mbps
- 4 Mbps to London, Netherland

These bits-per-second figure are not accurate, but helps painting the
picture I think.

It might be a good idea to contact the guys who mirrors Linux distro
and co in new Zeland (ftp://ucmirror.canterbury.ac.nz comes to my
mind)
