knowing that level(3) is one of the most serious deployments of
irr-based route filters and other prudent practices, perhaps we should
wait for a post mortem from level(3) before jumping to conclusions?
There's no magic bullet in updating BGP if a fundamental, verifiable
data model is not accepted and agreed upon.

the space of routing data validation is large, we can explore it at our
leisure, and we have been for some years.  but my point was that it is
silly to indulge in conjecturbation on the cause of the recent event and
excoriate l(3), hanaro, or john curran's grandmother until we have heard
from the folk who have actual data.
