GoKawiilFAA says root cause of nationwide flight ground stop still unidentified
FAA Administrator Bryan Bedford said officials have not pinpointed what caused instability in routers and networking equipment that led to the longest nationwide ground stop since 9/11. Transportation Secretary Sean Duffy named Cisco and L3Harris Technologies equipment as involved, and L3Harris said it is working with the FAA to investigate the conditions behind the November 13 stoppage.
GoKawiil's interpretation of the reporting above, not reported fact.
The uncertainty over the cause suggests the FAA opted to ground flights preemptively rather than risk losing sensor-to-aircraft connectivity, prioritizing caution over immediate operational continuity. Duffy's comment about being 'stuck with L3Harris' hints at frustration over dependence on legacy contractors while a fiber-optic upgrade, cited as over 70% complete, is still underway.
- FAA has not identified the root cause of the nationwide ground stop.
- Cisco and L3Harris networking equipment were both implicated in the disruption.
- L3Harris says it is cooperating with the FAA's investigation into the November 13 incident.
