I think in the case of my server, it will be somewhat meaningful, since
we peer with major North American IPv6 providers and don't have funky
tunnels to distant (network-wise) providers.

Sadly, I don't have shell access to any non-US machines to check on
connectivity, but there are a number of web-based traceroute servers
available.  See, for example,
http://dmoz.org/Computers/Internet/Protocols/IP/IPng/IPv6_Traceroute_Servers/

Here's a traceroute from ipng.nl:
Tracerouting to 3FFE:1CE1:2:180A:202:E3FF:FE00:4C75...

traceroute to 3FFE:1CE1:2:180A:202:E3FF:FE00:4C75 (3ffe:1ce1:2:180a:202:e3ff:fe00:4c75) from 2001:6e0::250:4ff:fe4a:7708, 30 hops max, 16 byte packets

done.

That looks really good.  Similar traceroutes from lava.net and a site in
Belgium looked about the same.  They all seem to be crossing the planet
only once, which is a good sign.  I wish I could find a traceroute server
in .jp or some other Asian country, since that's where IPv6 deployment
is most widespread.

I think it does make some sense to mention the US, because what's to
stop somebody from setting up an IPv6 mirror in some other country?
Would "USA (IPv6)" work?

noah
