News 6 reached out to Southwest Airlines, and the airline sent the following statement:
Southwest has resumed operations after temporarily pausing flight activity this morning to work through data connection issues resulting from a firewall failure. Early this morning, a vendor-supplied firewall went down and connection to some operational data was unexpectedly lost. Southwest Teams worked quickly to minimize flight disruptions. We ask that travelers use Southwest.com to check flight status or visit a Southwest Airlines Customer Service Agent at the airport for assistance with travel needs. We appreciate the patience of our Customers and Employees during this morning’s brief disruption.
This comes after the airline experienced a computer outage in a government system in January that delayed or canceled thousands of flights across the U.S.
The outage revealed how dependent the world’s largest economy is on air travel, and how dependent air travel is on an antiquated computer system called the Notice to Air Missions System, or NOTAM.

Before commencing a flight, pilots are required to consult NOTAMs, which list potential adverse impacts on flights, from runway construction to the potential for icing. The system used to be telephone-based, with pilots calling dedicated flight service stations for the information but has since moved online.
Longtime aviation insiders could not recall an outage of such magnitude caused by a technology breakdown. Some compared it to the nationwide shutdown of airspace after the terror attacks of September 2001.
