The Washington State Department of Transportation is blaming a “cybersecurity incident” for taking out parts of its website and app this week, disrupting the flow of travel-related information.

Outages which began Tuesday were ongoing as of Thursday morning. WSDOT shared updates on X in which the agency said traffic and mountain pass cameras had been restored on the app but not on the website.

WSDOT’s travel map, mobile app, ferry vessel watch and online freight permits remained out of service, and “work to restore them while safeguarding the systems continues,” WSDOT posted.

WSDOT said the cause of the incident is under investigation.

“We know this disruption is frustrating, we rely on the same disrupted tools and systems in our own travels,” another post on X read.

A banner at the top of the WSDOT website thanked users for their patience as the agency worked to get online tools back up and running.
