KING COUNTY, Wash. — Highline has notified parents that schools will remain closed on Tuesday as they continue to work to fix the technological issues caused by a possible cyberattack.

On Sunday Highline Public Schools announced that classes were canceled on Monday after the district said it detected ‘unauthorized activity’ on its technology systems.

The district has not disclosed what kind of unauthorized activity was discovered.

According to a note posted on the district website, staff has taken immediate action to isolate the impacted system.

The district said it is working closely with state and federal partners to rectify the issue.

The district-wide closure comes on what was supposed to be the first day of kindergarteners.

“We recognize the burden this decision places on both families and staff, but student safety is our top priority, and we cannot have school without these critical systems in place,” the district posted online.

For those looking to attend today’s scheduled vaccine clinic, the district said it has been moved to the Matt Griffin YMCA at 3595 South 188th Street in SeaTac, from 3:00 to 6:00 p.m. Registration is recommended for faster service: gethps.info/4dV5dTE
