Aurora Public Schools will delay start times for two hours on Thursday and Friday due to an ongoing internet outage affecting all campuses and offices.
The issue began early Monday morning, when staff detected "potential suspicious activity" on the district's network.
"As a precaution, we worked quickly to protect our systems, and at this time, we continue to work to bring back our systems and restore our technology infrastructure," wrote spokesperson Corey Christiansen.
APS also canceled a.m. preschool for Thursday. There are no scheduled preschool classes on Fridays. Schools will be closed Monday for Martin Luther King, Jr. Day.
The district is "making progress" and expects to be back in action by Tuesday, Jan. 21.
Christiansen said the district has "safety and security measures in place" to ensure that schools have communication channels and continue to operate safely. The school's public address systems are still working, and staff are able to take calls from families and respond to families' emails.
Staff have printed emergency contact information for families and security staff are on hand.
"While this has been extremely frustrating for our community, these measures were necessary to protect our technology infrastructure. At this time, we continue to respond to the outage and investigate the cause of the suspicious activity," Christiansen wrote.
Christiansen said on Wednesday afternoon that the district would soon send an update. APS serves more than 38,000 students across 59 schools.
