        Interesting, though they do guarantee that to NATO
circuits.  smd, are you able to get diverse local paths over there ?

NATO doesn't get guaranteed diverse circuits.  However, during an emergency,
NATO does get first dibs on any circuit still working.  So, if you have
diverse circuits, and one goes down, its possible your other circuit will
be pre-empted if it is the only way to restore the NATO circuit.

Nice.  Try explaining that in a customer outage notification:

"On Monday, June 11, at 9:30 am GMT, providernet suffered complete failure
of both circuits from London to Paris.  One line failed due to a fiber
cut, and NATO stole the other.  Network engineers, international
terrorists, and Slobodan Milosevic are currently working to restore
service."

Is it Friday yet?

Cheers.
