Lumen / Level3 filtergen is trimming these routes now.  Don't bother trying
to query filtergen.level3.net currently; server is full.  Small AS cone does
not equal small societal footprint & impact.  While I appreciate the
intention upthread of proxy registering at ATLDB, it really just distracted
from finding the root issue.
