    The FAA Outage Lays Bare an Essential System Everyone Hates

    The FAA Outage Lays Bare an Essential System Everyone Hates

    The United States Federal Aviation Administration today halted flights taking off across the country beginning early this morning and continuing until 9 am ET. The pause—the first of its kind in the US since the September 11, 2001 attacks—delayed thousands of flights and created a cascade of further delays and cancellations throughout the day. Those familiar with the FAA’s systems say the outage is unprecedented, but caps off years of frustration as the agency works to transition its complex processes to the cloud.

    The situation was caused by an outage in a critical system the FAA uses to distribute real-time data and warnings to pilots. Known as NOTAM (Notice to Air Mission) alerts, the system is vital for information sharing and coordinating many of the basic logistics of safe flying. 

    According to the FAA, the flight pause went into effect “to allow the agency to validate the integrity of flight and safety information.” The agency said in an update this evening that a preliminary investigation had traced the outage to “a damaged database file.” The White House said this morning that there was no evidence that the system blackout was caused by a cyberattack, but it was directing the Department of Transportation to conduct a thorough investigation of what caused the incident. 

    “This event today is more significant than a hurricane making landfall in the US, more significant than a blizzard shutting down an airport,” Michael McCormick, an assistant professor in the College of Aviation at Embry-Riddle Aeronautical University, told reporters at a press conference following the incident. “This had systemwide impact across the entire country.”  

    NAV Canada, a nonprofit corporation that serves as the FAA’s Canadian counterpart, said today that it had also experienced its own brief NOTAM system outage. Brian Boudreau, a spokesperson for the company, says it was investigating the “root cause of the failure” but that it did not believe the issue was related to the FAA’s earlier trouble.  

    The NOTAM system is decades old and widely criticized by pilots for being cumbersome and inefficient. NOTAM alerts can be tens or even hundreds of pages long, and are written in a sort of coded parallel language that has evolved over many years and out of numerous technologies, including Morse code, telegrams, and the radio navigation system Loran-C.
