A nationwide FAA outage that grounded flights in the US is under investigation, with the FBI reportedly examining whether a software update contributed to the communication problem affecting air traffic control.

Across the coverage, outlets cite that the FBI does not believe the issue was caused by a cyberattack or criminal activity. Bloomberg reports that the bureau is looking into whether the outage stemmed from a software update, while SecurityWeek similarly says officials see no evidence of hacking behind the ground stop. The Next Web also frames the story around the FBI’s probe into the software update, relying on reporting attributed to Bloomberg.

While the outlets agree on the central thrust—that investigators are assessing a software update and not treating it as a hack—the emphasis varies in how directly each outlet foregrounds the lack of cyberattack evidence versus the FBI’s specific line of inquiry.
