Duffy blames contractor & old equipment for FAA ground stop

BREAKING: Transportation Secretary Sean Duffy says investigators are looking into whether a contractor's installation error or a faulty router caused a failure in the nation's air traffic control system. The issue surfaced during an upgrade from copper to fiber connections, when a router being replaced began overwhelming other routers across the network. Officials are now investigating whether the disruption was caused by a contractor mistake or an equipment malfunction. Right now more than 3,000 flights are cancelled.
