Christian,
The terminology I used was incorrect. What I meant to say was:
"it appears that AS1853 is announcing a default route (to the
Looking Glass at VIX -> at least)." I was merely seeking an
explanation and wandering if this is what was really intended,
not knowing myself exactly what was intended by this announce.
Regards,
-Donner
p.s. Paul - if you want to forward this to NANOG for me...
