Re: goog fiber routing issue?

All my traceroutes (from inside or out) stop at the last non-Google
Fiber hop.  For example, from my home router:

traceroute to 2605:a601:f70:f0::1 (2605:a601:f70:f0::1), 30 hops max, 72
byte packets
 1  *  *  *

i think that is because the target is google business fiber and you're
home fiber.

atlas TraceMON (for 128292864) from within google fiber sure looks this
way https://archive.psg.com/250912.intra-gf-traces.jpg
