System Status
Announcement: On Thursday October 20th, 2022, the SciNet datacentre (which hosts Niagara and Mist) will undergo transformer maintenance from 7:30 am EDT to 5:00 pm EDT. At both the start and end of this maintenance window, all systems will need to be briefly shutdown and will not be accessible. Apart from that, during this window, login nodes will be accessible and part of Niagara will be available to run jobs. The Mist and Rouge clusters will be off for the entirety of this maintenance. Users are encouraged to submit Niagara jobs of about 1 to 2 hours in the days before the maintenance, as these could be run within the window of 8 AM and 5 PM EDT. Wed Oct 5, 2022, 12:10 PM EDT: A grid power glitch caused all compute nodes to reboot. Please resubmit your jobs. Mon Oct 3, 2022, 11:20 PM EDT: Niagara login nodes are accessible from outside again. Mon Oct 3, 2022, 9:20 PM EDT: Niagara login nodes are inaccessible from outside of the datacentre at the moment. As a work-around, ssh into mist.scinet.utoronto.ca and then ssh into e.g. nia-login01. Wed Sep 28, 2022, 1:15 PM EDT: The JupyterHub maintenance is finished and it is now accessible to users. Wed Sep 28, 2022, 1:00 PM EDT: The JupyterHub is to be rebooted for system upgrades.
