Notice of upcoming maintenance: Increased network security for Arbutus cloud

On Wednesday, November 27, Compute Canada's Arbutus Team will be installing a network security appliance on the commodity internet connection to Arbutus, Compute Canada's national cloud system. This work will be performed between 9:00 to 10:00 am (PST) / 12:00 to 13:00 pm (EST).

During this time, virtual machines on Arbutus will continue running and there is no network outage anticipated. This change will significantly improve the security posture of cloud instances and networks against attacks which originate from outside the national research network.

If you have any questions or concerns about this change, please contact
