According to CoinMeta, the Federal Aviation Administration (FAA) in the United States has lifted the nationwide flight suspension that had caused flights across the country to be halted due to communication disruptions. This move has cleared the way for airlines to resume operations after more than four hours. Airlines face the challenge of restoring their flight schedules, and the delays and cancellations caused by the suspension may continue to affect the aviation system for several hours. This nationwide flight suspension is only the third of its kind in U.S. history, as the FAA is dealing with aging air traffic control infrastructure and the pressure of modernization. The agency attributed the disruption to a temporary telecommunications issue, with the exact cause still under investigation. The Federal Bureau of Investigation (FBI) believes that the disruption was not caused by a cyberattack or criminal activity.
