J Root woes on v4

[Eric Dugas via NANOG <nanog () nanog org>]

Hello,

It seems that J Root has suboptimal routing over v4 but v6 is OK from my
POV in Montreal, Canada. Route changes occurred ~5h ago.

v4: ~260ms somewhere in Asia via our HE bilateral in Montreal, Canada
(AS-PATH 6939 45629 55423 55423 26415 396651 396651)

55423 might host a legit J Root node, but it should be exported outside
their region by AS45629 or HE.

v6: ~24ms in Chicago via Arelion IPT in Montreal, Canada
(AS-PATH 1299 7342 36631 36631)

This one looks legit.

Eric
