The Trillium login nodes and storage should be up by this evening. Tue 2026 July 21 05:00: Please be advised that the data center shutdown will impact all clusters. The outage is required due to electrical work being carried out by the local utility provider in the area. 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 22-26, 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: A 12-day-long shutdown of Trillium compute nodes will be required. During most of this time the Trillium login nodes, HPSS, Globus, storage and Open Ondemand will remain up, as well as the S4H, Balam, Neptune, and Teach Cluster. The latter services and systems will also briefly go down on July 21st when transformer maintenance will take place. More information and precise dates for the last maintenance shutdown will be announced later.
