Cascading Failures Could Crash the Global Internet

[Sean Donelan <sean () donelan com>]

Sigh, there are differences between tightly coupled networks, such as
the electric power grid and loosely couple networks like the Internet.
But there are also some similarities, such as electric grids use DC
interconnections to limit how far AC disturbances propagate; the
Internet uses AS interconnections to limit IGP disturbances from
propagating.
