Seattle Tacoma Airport Hit By Suspected Cyberattack; Operations Delayed

This vulnerability is the most recent incident to caused many at the airport to be without a flight for the time being.
 

System-Less In Seattle

The airport proclaimed on Saturday morning after 9 a.m. PT that terminals have been experiencing "isolated critical systems", making it difficult to commence flights as scheduled. The airport's official website (Link) also remains offline, so passengers are having a hard time checking flight statuses remotely.

According to FlightAware (https://www.flightaware.com/live/cancelled/today), a total of 281 flights were delayed on Saturday and Sunday, with 10 of those flights canceled. For what it's worth, 389 flights were delayed and eight were canceled on Friday, so it's unknown if the systems outage had impacted travelers sooner. 

As of Monday morning, there have been only 16 delays and three cancelations logged into FlightAware. According to Seattle-Tacoma airport's X account (@flySEA), crews are working to restore services and there has been no timetable for a full return.

The systems outage is less than 2 months coming off the Crowdstrike update bug that had caused a worldwide outage in July, rendering many flight and scheduling systems downed and leaving over a million customers stuck at airports (Link)
