Please review and refresh campus downtime procedures with all impacted teams. For any assistance needed in the preparation efforts of this event, please feel free to reach out to the Network Emergency Management Team at Networkem@hmhn.org. WHEN: 8:00 to 10:00 p.m. Sunday, December 3, 2023 ON CALL: If you are a team member on-call during this time, you will NOT have network remote access, and will only be able to provide support while onsite within the HMH network.

The Service Desk will be fully staffed during the downtime and will be available as systems are brought back online. This downtime will test the network’s "Airplane Mode" that in the case of a large-scale malware/cyberattack will block all inbound and outbound traffic at the network perimeter. This is part of HMH's defenses against cyberattack.
