ATT (AS7018) cannot reach AS31334

Hi -

I am a ATT customer unable to reach AS31334. Is anyone on this list
able to check into this? It works from non-ATT route-servers I have
tested on.

ATT route-server

From what I can see, 31334 is sending prefixes covering this IP to

upstreams 1273 and 6939 (possibly others, but that's what I saw). Neither
of these networks propagate those prefixes into 7018 directly or indirectly
so we have no path to get there. I would encourage 31334 to check with
their upstreams to understand why the routes don't get sent to 7018.
