I'd only looked using their Ashburn location.  So, Verizon does receive 
the route, but doesn't appear to propagate it beyond the APAC region.

That could still be either network's choice.  The fact that their looking 
glass doesn't show anything for "Communities:" is suspicious to me, 
because I seriously doubt VZ isn't community tagging all I'm 
assuming there's a filter that's removing those for display...but then why 
even include the Communities: line in the output?...or maybe they've 
migrated to large communities and their looking glass hasn't been updated 
to display those?
