Clearly you don't know what you are talking about either!!
I believe that he knows exactly what he was talking about. The contingency system (I helped design/install it) is a 'clear the skies' system not designed for as failure like today's. The amount of traffic it could move is far lower than that which was moved in today's failure mode and the risk of swinging all the data/comms over to the contingency would require a much more dire failure before it would be even considered.
