FWIW, eftps.gov is also unreachable via ipv6. I tried all of miredo,
and my home Sixxs tunnel, and a HE tunnel from somewhere else.  I used
the 4or6 plugin to temporarily disable ipv6 and both sites loaded
straight away.

eftps.gov and pay.gov appear to be managed separately since both their
ipv4 and ipv6 netblocks are not in the same netblocks, and my path to
them is not the same:

eftps.gov has IPv6 address 2620:10f:400e:a::13

I was hoping an eftps.gov or pay.gov employee was casting an eye this
way, but it doesn't look like anybody from there is subscribed to
NANOG.
