Very interesting. They say that neither the Baltimore train wreck nor the
WTC attacks destabilized the global Internet (HAH! ;-) But there does seem
to be a high correlation between Code Red and Internet instability, as well
as between Nimbda and Internet instability.
They don't go so far as to say there is a cause and effect. One does wonder
why a high rate of traffic (due to the worms) would cause problems for BGP.
I guess BGP sessions could time out if the congestion got too bad, but that
would point to a rather fundamental flaw with BGP implementations if that
were the case?
Near the end they say another hypothesis is that congestion due to worm
traffic at the Internet's edge causes many network operators from
corporations and small ISPs to reboot or reconfigure their border routers
(an "epidemic of sysadmin panic".) So, stay calm folks. ;-)
Thanks for sharing the info. We should all stay posted for more news on
this front.
