Scheduled Maintenance
Graham Planned Outage - Arrêt planifié

Due to site electrical changes, there will be a brief outage of some Graham components, for up to 2 hours, on Wednesday, September 25.

This will affect most compute nodes, so the scheduler will be configured to avoid scheduling jobs that would be affected. Login, storage and cloud nodes will NOT be affected.

Scheduled maintenance for Arbutus - September 25 / Maintenance sur Arbutus le 25 septembre 2019
