Even if we were to model it, the best data we could get for
the "Internet" would be BGP routing tables. These are also
subjectve views of the rest of the net. We could take a full 
table, map all the ASN adjacencies, and then pick arbtrary
ASN's to "fail", then see who is still connected, but we are 
still dealing with connectivity relatve to us and our peers, 
even 5+ AS-hops away. 

I would imagine this is one of the tasks CAIDA.org is probably 
working on, as it seems to fall within their mission. 

So even if we all agreed upon a common disaster to hypothesize 
on, there would be little common ground to be had, as our 
interpretations could only be political arguments over what is
most important, because there is no technically objective view
of the network to forge agreement on.
