Network Outage Update 09.05.2023 3:00PM
Many K12 schools experienced network slowness this morning due to a hardware service failure serving the ICN K12 Broadband Network. A security configuration change was made Friday night to add additional security measures to the network which appears to have resulted in key hardware CPU failure once school resumed this morning and bandwidth demand reached normal levels. The change was reversed and service restored.
