Maybe it's time to talk about rational routing

Good news down under, it seems that TelstraClear is now supporting
native IPv6, announced in Australia but observable in New Zealand too,
with much less HE tunnel than before.

However, it seems to be time for a discussion about routing policy.
The traceroute below reminds me of IPv4 around 1990. Is it really
optimal to route from Auckland to Brisbane via Hong Kong and Los
Angeles? Of course there are all the usual commercial constraints
on policy, but this seems to be worse than that.
