Is this a hack?
No — this is not a hack or cyberattack.
Officials, including Homeland Security Secretary Markwayne Mullin, say there is zero evidence of a cyberattack; investigators are still examining the cause.
Root cause
The FAA describes a temporary telecommunications outage affecting air route traffic control centers. CBS News, citing multiple sources, reported that an update to the L3Harris-run network caused a reboot and crash, and Duffy blamed overloaded routers and aging equipment. None of these causes is confirmed by the FAA.
