Alaska Airlines experienced a three-hour ground stop Sunday night due to a hardware failure in its data centers, resulting in approximately 200 flight cancellations. The outage, impacting Alaska and Horizon Air flights, affected key operational systems. The airline assures the safety of flights was not compromised and is working with a third-party vendor to replace the faulty hardware. The incident is unrelated to cybersecurity issues, though Alaska Airlines has faced similar technology-related disruptions in the past. Aviation analyst John Nance emphasized the airline's prioritization of safety in grounding flights.
