And as an interesting counterpoint to this, this graph shows
the number of BGP routing updates received at MIT before, during,
and after the worm (3 day window).  Tim's plots showed that the
number of actual routes at the routers he watched was down
significantly - these plots show that the actual BGP traffic
was up quite a bit.  Probably the withdrawals that were taking
routes away from routeviews...
