I'm not sure then of the impact. Additionally, a majority of peering, big peering, isn't on public exchanges is it? So, you'd have to find all the places that the larger providers connect to eachother and perhaps target these. Even with this there are the public exchanges so things 'should' fail over to them... Overall I recall the outcome from the study being that the internet was a significantly difficult target to completely kill, and even making a performance impact was somewhat difficult... I will say though, that my memory is a bit foggy on this particular study, I didn't participate in it, and I didn't read the actual results. Any info I have on it is third hand via a lawyer, so take all this with a grain of salt :) > > > > The other thing to think about is that the physical transport will be > > affected as well.

This was about the result I heard, you can easily cut out 'mom and pop' ISP, but cutting out a large provider is a tougher task with bombs... we already know its possible with the right routing 'update' :(
