Whoops, spoke too soon. While HE indeed seems to use the transits to reach Cogent, they only do this over v4. IPv6 packets are indeed dropped on the first border. Sorry for the noise. core1.fmt1.he.net> traceroute ipv6 2001:550:2:d::a:2 numericTarget 2001:550:2:d::a:2 Hop Start 1 Hop End 30 Hop Packet 1 Packet 2 Packet 3 Hostname 1 * * * ? 2 * * * ? 3 * * * ? 4 * * * ?

It is worth noting that HE indeed provides the full view, it's the other side that has an issue.
(Since HE isn't really a tier 1, their transit relationships with Telia and other carriers "save" them)
Cogent -> HE dies with unreachable on the first hop though, and that's an issue for Cogent customers.

Or, if you feel that Cogent's stubborn insistence on partitioning the global v6 internet if A does not peer with B, then for all A and B they are evil partitioners?
can we lower the rhetoric?
They both loses on this. In fact anyone claiming tier 1 status loses here, because this illustrates why you can never be single homed on a tier 1 network. These guys simply do not have the full internet.
