  • •Officials confirmed zero evidence of malicious activity or foreign involvement.
  • •Ongoing investigations may uncover vulnerabilities in the FAA's aging infrastructure.

On November 13, 2026, the FAA experienced a nationwide ground stop due to overloads in legacy air traffic control systems, specifically in switches and routers managed by L3Harris Technologies. Officials from the Department of Homeland Security and FAA confirmed there was no evidence of a cyberattack or malicious intrusion, attributing the outage to a telecommunications failure during system upgrades. Secretary Markwayne Mullin stated there were zero signs of nefarious activity, and the FBI is investigating a possible software update trigger. The incident echoes the 2023 NOTAM database outage, leading to a 96.3% market-implied probability that the outage was not caused by a cyberattack. Ongoing reviews by the NSA and DHS may reveal vulnerabilities in the aging infrastructure or contractor processes.
