No, I mean:  Why didn't *your upstream's* routes fall back to *their* other
peers, who should be perfectly capable of transiting those packets?

The thinly veiled implication there is that "full mesh" is not a long term
effective way to run the backbone level transit, because dropping one peer
without an alternate path means that we get broken transit.  Yum.
