consistency sort of thing; routes were still carrying packets
to the interconnect, but the packets were not successfully
making it across the interconnect.  I would hazard a guess
that had the link truly gone down in the classic sense, BGP
would have done the more proper thing, and found a different
path for the routes to propagate along.

Again, this is speculation from the outside, based on the
path packets were taking before dropping on the floor.
