Alaska Airlines Faces Major IT Outage, Grounding Flights in Seattle

The outage, caused by a certificate issue, disrupted operations Sunday night but has since been resolved.

Alaska Airlines experienced a significant IT outage on Sunday evening, leading to a ground stop at Seattle-Tacoma International Airport.
The airline cited a certificate issue as the cause, ruling out cyberattacks or unauthorized activity.
The disruption affected multiple systems, including the airline's app and website, causing delays and some flight cancellations.
Operations resumed by 10 p.m. local time, but residual impacts on flights were expected.
This incident follows a recent cyberattack on the Port of Seattle, which had already strained airport operations.
