FAA says malfunctioning Arkansas router caused nationwide flight ground stop

The Federal Aviation Administration identified a malfunctioning router at an FAA radio site in El Dorado, Arkansas, as the cause of a nationwide flight ground stop on Friday, according to a report by the Wall Street Journal cited by the New York Post.

What happened

• A newly installed router at the FAA radio site in El Dorado, Arkansas, flooded the network with excessive data traffic, disrupting communications between pilots and air traffic controllers, according to the Wall Street Journal.
• The outage affected 17 of the FAA’s 22 high-altitude control centers.
• More than 3,500 flights were grounded during the roughly five-hour shutdown.
• Officials are investigating whether defective equipment or installation errors by contractor L3Harris caused the failure.
• Another router in Amarillo, in the Texas panhandle, is also being eyed as contributing to the outage.

Official statements

Rebecca Guy, the FAA’s technology chief, said on Saturday: “We saw two places that were actually pinging our network at a very high rate, a thousand connections over every four to five seconds.”

The FAA states that there was no evidence of a cyber attack.

El Dorado is a city of about 22,000 people some 210 miles northeast of Dallas.

Why it matters

The disruption grounded flights across the United States and highlighted vulnerabilities in the nation’s air traffic control technology infrastructure.
