Re: Bad IPv6 connectivity or why not to announce more specifics (Was:IPv6 news)

My box that gets IPv6 connectivity from Kewlio (set up via the SixXS
tunnel broker) has a fairly short route which doesn't seem to go via
Japan

traceroute6 to time20.stupi.se (2001:440:1880:1000::20) from 2001:4bd0:202a::1, 64 hops max, 12 byte packets

Though my other box (with connectivity via the BT Exact tunnel broker)
goes via Japan...
