It seems to me that the recent discussion between Leo Bicknell and Lamar
Owen is relevant. A network partition affecting hundreds of thousands
(millions according to the Boston Globe article) is closely akin to a
natural disaster. In this case, an _unnatural_ disaster.
I remember presenting a paper at IETF over a decade ago about assigning
IP addresses to exchanges instead of carriers. That would allow rapid
failover, and promote competition.
Therefore, I propose that we identify those ISPs moving from Level3 to
Cogent that are also connected to an *IX. The IP block should be
reassigned by the registry to the IX.
We should encourage everybody else moving that requires a circuit change
to connect to an IX where Cogent is present.
That should help routing tables immensely!
