A “possible cyberattack” led to an internet outage and web system issues at Seattle-Tacoma International Airport on Saturday, the Port of Seattle reported. The agency posted an initial alert on the social media platform X shortly after 9 a.m., advising passengers to check with their airlines for the latest information on their flights. In an afternoon update, the Port confirmed the possibility of a cyberattack and said it had “isolated critical systems.” The Port did not have a timeline for restoration.
