goog fiber routing issue?

[Randy Bush via NANOG <nanog () lists nanog org>]

would appreciate some help.  i suspect goog fiber is announcing
inconsistently.  i wrote to noc () googlefiber net and crickets.

atlas essenitally says no route, see attached porn (or
https://archive.psg.com/250912.gf-traces.jpg in case list does not
allow).  and see https://atlas.ripe.net/measurements/128265158/

but rv says gf announces the /31

      and many more

i is as if they are announcing to rv but not peers.  but that is pure
conjecture.
