A damaged fiber-optic cable disrupted air traffic at Houston’s George Bush Intercontinental Airport (IAH) on the evening of October 13, 2026, prompting the Federal Aviation Administration (FAA) to issue a ground stop and causing significant flight delays.
The disruption was caused by a construction contractor who severed the fiber-optic cable earlier that day, affecting major communication systems crucial for airport and FAA operations. Repair crews were deployed onsite at IAH to restore the line, while Houston Airports coordinated efforts with airlines and U.S. Customs and Border Protection to manage the impact on operations.
FAA Advisory and Operational Restrictions
The FAA issued an operations advisory stating,
“IAH has lost major communications and users can expect the current ground stop to be extended and expanded.” This advisory was released on the evening of October 13, indicating that flight restrictions might continue and additional delays or cancellations could occur as the situation evolves.
Scope of Impact and Related Airports
The FAA confirmed that William P. Hobby Airport and other airports within the Houston terminal area were not affected by the outage. However, international arrivals at IAH experienced longer processing times through U.S. Customs due to operational disruptions. Houston Airports warned of the possibility of ongoing delays and cancellations throughout the evening while repair work
proceeded.
Context of Similar Incidents and Infrastructure Efforts
This fiber-optic cable disruption at IAH follows a similar incident at Raleigh-Durham International Airport on October 12, where contractor work severed a fiber-optic cable, triggering multiple FAA ground stops, flight cancellations, and arrival delays exceeding two hours. Both incidents highlight vulnerabilities in current air traffic communication infrastructure, which the FAA is actively working to modernize.
