I'm currently unable to reach security.debian.org (2001:8d8:2:1:6564:a62:0:2) through IPv6.
donald:~# traceroute -M tcpconn -p 80 wieck.debian.org -n -6 traceroute to wieck.debian.org (2001:8d8:2:1:6564:a62:0:2), 30 hops max, 80 byte packets
It helps if you mention your own IP address. Using 2001:7a8:820:1::1 instead, I get this in the reverse direction (from wieck): traceroute to 2001:7a8:820:1::1 (2001:7a8:820:1::1), 30 hops max, 40 byte packets 1 vl-121.gw-dists-a.bs.ka.oneandone.net (2001:8d8:2:1::1) 1.530 ms 1.614 ms 1.709 ms 2 te-1-2.bb-c.bs.kae.de.oneandone.net (2001:8d8:0:5::1) 1.116 ms 1.169 ms 1.104 ms 3 te-4-2.bb-c.act.fra.de.oneandone.net (2001:8d8:0:2::11) 3.479 ms 3.540 ms 3.591 ms 4 te-1-1.bb-c.nkf.ams.nl.oneandone.net (2001:8d8:0:2::9) 10.139 ms 10.200 ms 10.247 ms 5 te-1-2.bb-c.the.lon.gb.oneandone.net (2001:8d8:0:2::5) 17.257 ms 17.321 ms 17.377 ms 6 linx.he.net (2001:7f8:4::1b1b:1) 17.281 ms 16.399 ms 16.456 ms 7 gige-g0-1.tserv17.lon1.ipv6.he.net (2001:470:0:a3::2) 16.546 ms 16.562 ms 16.512 ms 8 * * * [and nothing more] A traceroute from 2001:14b0:200:6::4 looks similar, despite taking a different entry point into HE: traceroute to 2001:7a8:820:1::1 (2001:7a8:820:1::1) from 2001:14b0:200:6::4, 30 hops max, 24 byte packets 1 2001:14b0:200:6::3 (2001:14b0:200:6::3) 27.324 ms 29.593 ms 26.593 ms 2 2a01:1e8:2:3::1 (2a01:1e8:2:3::1) 26.827 ms 26.772 ms * 3 2a01:1e8:2:4::1 (2a01:1e8:2:4::1) 30.685 ms 30.684 ms 30.767 ms 4 de-cix.he.net (2001:7f8::1b1b:0:1) 31.821 ms 35.31 ms 33.465 ms 5 gige-g0-1.tserv18.fra1.ipv6.he.net (2001:470:0:a5::2) 33.738 ms 33.368 ms 30.792 ms 6 * * * So this seems to be something beyound our (that is, Debian's) control, assuming that 2001:7a8:820:1::1 is as good as the IP address you've actually been assigned.
