Watching the looking glasses reveals that 6net/geant/dante simply don't peer enough with commercial ISP's. Good example is the www.deepspace6.net thread. For example, a simply trace from my home to that box: traceroute to deepspace6.net (3ffe:8300:0:1:10:a7ff:fe16:27f4) from 3ffe:8114:2000:240:290:27ff:fe24:bbab, 30 hops max, 16 byte packets 1 purgatory.unfix.org (3ffe:8114:2000:240:290:27ff:fe24:c19f) 2.6 ms 2.216 ms 2.078 ms 2 gw-20.ams-02.nl.sixxs.net (3ffe:8114:1000::26) 20.494 ms 21.748 ms 21.354 ms 3 2001:6e0::2 (2001:6e0::2) 20.647 ms 21.43 ms 20.869 ms 4 gw-viagenie-cnit.ipv6.cnit.it (3ffe:830f::3) 127.75 ms 127.818 ms 128.406 ms 5 gw-cnit-viagenie.ipv6.cnit.it (3ffe:830f::2) 292.836 ms * 292.115 ms 6 gw-fe-na.ipv6.cnit.it (3ffe:8300::4) 314.947 ms * 316.817 ms 7 3ffe:8300:0:1:10:a7ff:fe16:27f4 (3ffe:8300:0:1:10:a7ff:fe16:27f4) 318.12 ms 316.753 ms 320.819 ms gw-viagenie-cnit, aha we are going over the US? That would look like intouch at AMS-IX would have bad connectivity, even though I know that AMS-IX is one of the better places to peer with IPv6.

Not traceable though, and ofcourse quite asynchronous... </sarcasme> Greets, Jeroen
