The plot thickens: On AWS’ IPv6 reachability page (http://ipv6.ec2-reachability.amazonaws.com/) I see a number of errors:
And using RIPEs Atlas tool it’s clear that a least five other probes from the same AS as me have similar reachability issues against US West Oregon ::ec2 - but not “the other US West Oregon (::36c8:1)”
That’s kind of weird, but I guess I’ll have to get in touch with my ISP to further troubleshoot this one.
