US officials have attributed the November 13 FAA nationwide ground stop to legacy telecommunications infrastructure failures, including overloaded switches and routers in the FTI network managed by L3Harris Technologies that produced inconsistent data during patching of new equipment. Homeland Security Secretary Markwayne Mullin and Transportation Secretary Sean Duffy reported zero evidence of hacking, foreign actor involvement, or malicious access, with agencies including the FBI, NSA, and CISA finding no footprints or claims of responsibility. This technical diagnosis of aging hardware and mechanical overload has driven near-certain trader consensus against foreign attribution. While the probe continues and a software update remains under review, any reversal would require substantial new indicators contradicting the current findings.
