[AusNOG] HE Routing (not a joke)

[Gavin Tweedie]

TPG buys transit from HE /in the US/ so routing via the US is expected,
twice.
TPG SYD -> TPG SJC -> HE SJC -> HE SYD -> HE SJC -> TPG SJC -> TPG SYD

Yours looks like it's staying in Sydney on the way there, and coming back
via the US I agree.. You don't have any indications in your traceroute what
your source ASN is, but I'm going to guess that your ASN buys transit from
HE, or someone who buys from HE would that be right?

Hurricane do have a LG @ https://lg.he.net/ which might help you work out
the reverse path.
