Fragile Critical Infrastructure Needs Protection

The recent outage of the Federal Aviation Administration’s Notice to Air Missions (NOTAM) Pilot-Alert system, which triggered a 90 minute “ground stop” delayed over 9 thousand flights and was behind the cancelation of 1300, leaving countless flyers stranded and planes grounded. The outage shows the fragility of the transportation system, one of many components of the nation’s overall critical infrastructure sectors.

The system at the center of this incident, alerts pilots about potential hazards to their flights, including closed runways, outages, other important safety data. It is not used to fly the plane or by Air Traffic Controllers to keep aircraft at safe distances.

The system initially failed at 3:28 p.m. on Tuesday. By 7:20 a.m. Wednesday the FAA issued a ‘ground-stop’ for all U.S. airlines to pause domestic departures. The ‘ground-stop’ order was subsequently lifted by 9 a.m. Wednesday.

Initial reports point to corrupted system files which required a fix and system reboot. The backup system were also reliant on the corrupted data feed, thereby creating a Single Point of Failure (SPOF).
