We are working on the other systems still. Tue Sep 16, 2025, 5:45 pm: Unfortunately, we cannot bring all systems up yet because we are waiting for a spare part for the cooling system that will be brought tomorrow. In the meantime, we have managed to keep the Trillium login nodes up, but not other systems. Tue Sep 16, 2025, from 7:00 am to 5:00 pm (EDT): The SciNet datacentre will undergo maintenance of several critical parts of the centre. This will require a full shutdown of all SciNet systems (Trillium, Niagara, Mist, HPSS, Rouge, Teach, as well as hosted equipment). This will also be the time that the Mist cluster gets decommissioned. Fri Sep 12 22:03:17 EDT 2025: HPSS software and OS upgrades are finished. Tue Sep 9 17:05:38 EDT 2025: Starting tomorrow, Sep/10, and for the following 3 days HPSS will be down for software and OS upgrades. We will strive to finish sooner, at which time we will make the system available to users again. Mist/Niagara Decommissioning Schedule September 4, 2025 Niagara reduced to 863 compute nodes. September 9, 2025 Niagara's Open OnDemand decommissioned. Brief data centre connection outage at 9 AM EDT Niagara reduced to 647 compute nodes at end of day.
