I seem to recall a massive routing failure in October
which was caused by BGP getting imported to a major

The core ${VENDOR 1}routers were able to handle the
influx of routes, but the edge ${VENDOR 2} routers
could not handle the influx - so the failure didn't
exactly cascade, but did more of a ripple.  However,
the reloading of all of the edge devices increased the
BGP instability.
