Highline Public Schools, a 17,500-student district south of Seattle, canceled classes for Monday due to a cyberattack.
In an announcement posted Sunday, the district said it had “detected unauthorized activity on our technology systems and have taken immediate action to isolate critical systems. We are working closely with third-party, state and federal partners to safely restore and test our systems.”
The closure impacts all school activities, athletics and meetings for the district.
Highline Public Schools only started classes on Wednesday, and the first day of kindergarten was scheduled for Monday. They will determine by 2 p.m. if the closure will continue into Tuesday.
