ROCHESTER, Minn. – Rochester School employees have been told to reset their passwords as a first step in restoring the system’s disabled computer network. Once staff passwords are reset, the process can begin to restore student access to digital learning programs. The system has been dead since a cyber-attack from an unknown outside source was detected April 6. The cyberattack shut down everything, including systems for heating and cooling, payroll, and bell schedules. A few “hot spots” have been set up for staff to resume some limited functions.
