Trillium AI Expansion Installation Maintenance Shutdown Schedule
- May 26/27, 2026: Shutdown of the Trillium compute nodes and HPSS, starting at 4 AM EDT on May 26th. The Trillium login nodes as well as OnDemand, the Teach cluster, and Balam, will remain available during this maintenance. HPSS will be back in service later on the same day (May 26th), while the Trillium compute nodes are expected to be back in service at some time on May 27th.
- June 9/10, 2026: A multi-day chiller maintenance; this will involve a shutdown of all systems.
- June 22-25, 2026: A 4-day full datacentre shutdown. The SciNet datacentre will undergo maintenance of several critical parts of the centre. This will require a full shutdown of all SciNet systems (Trillium, Balam, S4H, HPSS, Teach, as well as hosted equipment).
- July 13-24, 2026 (tentative): A two-week long shutdown of Trillium compute nodes will be required. During most of this time the Trillium login nodes, storage and Open Ondemand will remain up, except for a one-day power shutdown within this period (currently planned for July 22nd).
More information and precise dates for the last maintenance shutdown will be announced later.
Wed Apr 30, 2026, 3:00 pm: System have been updated to mitigate known security risks, and are back in service. Note that no actual security breaches were found.
Wed Apr 29, 2026, 5:25 pm: For security reasons, login access to all systems has been disabled, as have OnDemand Apps. Compute jobs are still allowed to run.
Thu Apr 23, 2026, 10:00 am: The Trillium file system has issues and may be slow on certain nodes. We are still investigating.
