Internet vulnerabilities

["Jason Lewis" <jlewis () packetnexus com>]

There is a lot of news lately about terrorist groups doing recon on
potential targets.  The stories got me thinking.

What are the real threats to the global Internet?

I am looking for anything that might be a potential attack point.  I don't
want to start a flame war, but any interesting or even way out there idea
is welcome.

Is it feasible that a coordinated attack could shutdown the entire net?  I
am not talking DDoS.  What if someone actually had the skills to disrupt
BGP on a widescale?
