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. randy
