Beginning Tuesday, July 28, 2026, TSS will be unavailable nightly (including weekends) from 11:00 p.m. – 7:00 a.m. PDT to support issue resolution, data migration activities and other essential transition work.
This maintenance window is expected to continue throughout the initial TSS launch phase and is crucial to promptly resolving issues identified by the campus community while minimizing impact to users during the day. We recognize this downtime will impact your ability to complete tasks in TSS during these hours and appreciate your understanding and patience during this time.
Deadlines for tasks completed in TSS that were previously at 11:59 p.m. PDT will shift to 10:59 p.m. PDT or earlier to accommodate the planned maintenance window.
Please plan TSS-dependent work outside these maintenance hours. Visit theUC San Diego ITS Systems Status page for current incidents and service updates related to TSS.
We appreciate your feedback and flexibility as we continue refining the TSS experience for the campus community.
