Dear Campus Community,

Please be advised that all IT-reliant campus services will experience a scheduled unavailability between 6:00 AM to 6:00 PM on September 6, 2025. 

This essential downtime is dedicated to the critical second phase of our data center Uninterruptible Power Supply (UPS) installation. This vital project is led by our colleagues in Planning, Design, and Construction (PD&C) and Facilities Services (FS), in partnership with Information Technology Solutions (ITS), to enhance the resilience and reliability of our IT infrastructure.

During this maintenance window, a wide range of services will be impacted, including but not limited to: single sign-on (SSO) services, campus network connectivity, access to online applications, email services, phone lines, and various departmental systems. However, campus users may use Zoom Phone to contact campus emergency services by installing the Zoom mobile app on their devices and signing in using their UCR credentials ahead of the planned maintenance period. Please also note that emergency services can be reached by using cellular data to make the call.

We understand the critical nature of these services and have carefully planned this window to minimize disruption.

For a comprehensive list of all impacted services and to stay informed on the progress of this important maintenance work, please regularly check techalerts.ucr.edu (note: during a campus network outage UCR TechAlerts is accessible via cellular data and non-campus networks). This site will be updated in real time with any new information or changes to the schedule.

It is important to note that ITS does not anticipate service disruptions outside of the timeframe mentioned above. In the event you experience a service disruption outside of the scheduled maintenance window, please report it at https://its.ucr.edu/help or 951-827-4848.

We sincerely apologize for any inconvenience this necessary upgrade may cause to your work or studies. We deeply appreciate your understanding and cooperation as we undertake this significant improvement to our IT infrastructure, which is crucial for ensuring a stable and robust digital environment for our entire campus community.
