I think what's going on is that packets from www.ietf.org don't make it back to my ISP. A ping6 or traceroute6 doesn't show any ICMP errors and TCP sessions don't connect so it's not a PMTUD problem. So it's an actual timeout. I also just started noticing this, that is, that it does not work. And there is a very simple explanation for this: 6bone space.
We (OCCAID) had recently turned up peering with a few networks (including HE and others) and as a result our outbound path to HEAnet and other networks had changed.
Some of the abrupt route changes are being corrected today evening and hopefully should resolve pMTU problems in reaching www.ietf.org. If you continue to experience trouble in reaching thru OCCAID via IPv6, please don't hesitate to drop me a line in private.

that was quick, although I tunneling via freenet6. vrode@promiscious:/etc/ppp/peers$ traceroute6 www.ietf.org traceroute to www.ietf.org (2610:a0:c779:b::d1ad:35b4) from 2001:5c0:8fff:ffff::a5, 30 hops max, 16 byte packets 1 2001:5c0:8fff:ffff::a4 (2001:5c0:8fff:ffff::a4) 91.114 ms 90.643 ms 92.29 ms 2 freenet6.hexago.com (2001:5c0:0:5::114) 95.166 ms 102.207 ms 95.866 ms 3 if-5-0-1.6bb1.mtt-montreal.ipv6.teleglobe.net (2001:5a0:300::5) 89.454 ms 120.386 ms 92.113 ms 4 if-1-0.mcore3.mtt-montreal.ipv6.teleglobe.net (2001:5a0:300:100::1) 90.882 ms 92.495 ms 91.239 ms 5 if-13-0.mcore4.nqt-newyork.ipv6.teleglobe.net (2001:5a0:300:100::2) 96.672 ms 97.731 ms 97.782 ms 6 2001:5a0:400:200::1 (2001:5a0:400:200::1) 107.734 ms 96.951 ms 97.486 ms 7 2001:5a0:600:200::1 (2001:5a0:600:200::1) 107.223 ms 105.586 ms 103.39 ms 8 2001:5a0:600:200::5 (2001:5a0:600:200::5) 104.942 ms 106.728 ms 102.465 ms 9 2001:5a0:600::5 (2001:5a0:600::5) 107.945 ms 104.898 ms 103.782 ms 10 equinix6-was.ip.tiscali.net (2001:504:0:2::3257:1) 107.448 ms 109.082 ms 107.891 ms 11 equi6ix-ash.ipv6.us.occaid.net (2001:504:0:2:0:3:71:1) 223.532 ms 217.531 ms 218.709 ms 12 unassigned.in6.twdx.net (2001:4830:e6:d::2) 219.648 ms 221.496 ms 223.614 ms 13 stsc350a-eth3c0.va.neustar.com (2610:a0:c779::fe) 228.079 ms 227.053 ms 226.536 ms 14 www.ietf.ORG (2610:a0:c779:b::d1ad:35b4) 226.191 ms 227.959 ms 219.163 ms regards, /virendra -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGXdovpbZvCIJx1bcRAu0lAJ4ldNWYXCvBf4Vtvkdih8WknZc5XwCfdKKy UsquQuxR+AytwKrfuOF0MlM= =oJoI -----END PGP SIGNATURE-----
