Overview

• Controllers reported losing radar and phone links around early afternoon, prompting an immediate ground stop at Dallas/Fort Worth International and Dallas Love Field.
• The ground stop was lifted about 3:30 p.m. local time and replaced with metered arrivals, but significant delays, cancellations and some diversions persisted into the evening.
• FlightAware data showed nearly 700 delays and about 200 cancellations at DFW by late afternoon, with roughly 160 delays at Love Field.
• Flights diverted to other airports, including Oklahoma City, and ripple effects reached Phoenix Sky Harbor with dozens of delays and some cancellations.
• LiveATC audio captured towers halting departures due to lost contact with approach control, as the FAA worked with the phone carrier to restore service and determine the cause.
