Which had more impact on the the net?
An interesting question... I'm not sure that they're directly comparable. As Patrick pointed out, they have different side effects.
1. Destruction in New York City Sept 11 and following days 2. Nimda virus/worm on Sept Sept 18 and following days 3. Multiple fiber cuts on Sept 26
1. Damage focused at selected vertices 2. Congestion across the entire mesh 3. Damage along selected edges. Viewing the Internet as one large graph, all three affected different portions. When damage occurs, spokes disappear, and nearby vertices/edges become more congested. This is probably one very good reason that big providers demand peering in >= { 3 | 4 | however many } locations in different regions across the country: Performance might plummet in the event of damage, but there are alternate routes.[1] Multiple fiber cuts _did_ elicit a curious thought, though: Terrorists get ahold of backhoes and fiber maps. Eek. [1] This assumes that, when an edge or vertex disappears, the providers peering will route traffic "down the road". This is an administrative issue, but at least the infrastructure for a survivable network is in place.
