During the maintenance window, Top Hat may be unavailable and visitors will see a maintenance page. Any educator who has made an assignment due during or shortly after the maintenance window should consider changing the due date/time so that students have adequate time to complete them.

There will be a scheduled firmware upgrade on the campus data switches in Adler Journalism and Mass Communication (AJB) and the College of Public Health Building (CPHB).

During the maintenance window, network services may experience a brief interruption while the switches reboot. Expected downtime is approximately 10–20 minutes.

Please plan accordingly and complete any critical tasks prior to the maintenance window. We apologize for any inconvenience and appreciate your understanding.

Network Engineering Services will be upgrading the campus wired infrastructure. During this upgrade, wired and wireless connectivity will be down.

We will be adding additional resources to these systems to improve performance and enhance network redundancy. We recommend saving and closing all files stored on LSS before the maintenance occurs to prevent data loss or corruption.
