FAA employees disabled a feature across the agency's Juniper routers after it overloaded the communications network during Friday's nationwide flight ground stop, Tom's Hardware reported. The Wall Street Journal reported that a newly installed router began broadcasting widely across the network.

The FAA traced heavy traffic to sites in El Dorado, Arkansas, and Amarillo, Texas. Technology chief Rebecca Guy said the sites generated a thousand connections every four to five seconds. Restoring normal communications took about four hours.

HPE said the routers appeared to work as intended and had not failed. The FAA is investigating whether installation, configuration or the equipment caused the incident.
