Outage Notice: Rolling Reboots of QRIScloud Compute Nodes: 5pm 17 September 2020 - 9am 18 September 2020

Follow

We have detected performance issues with some of the compute nodes in the QRIScloud Availability Zone of the Nectar Research Cloud.

Issues were first identified on the 16th of September and have become more widespread through the course of today. A restart of the most affected compute node has significantly improved the situation for Virtual Machine (VM) instances running on that compute node.

Unfortunately, due to the nature of the issue, we cannot perform these restarts in a non-impacting manner and will need to perform rolling restarts.

All standard compute nodes are showing signs of these issues. Currently, the NSP compute nodes appear to be unaffected.

Rolling restarts across the rest of the affected compute nodes will be ongoing from:

5:00pm 17th September 2020 to 9:00am 18th September 2020


Virtual Machine instances will be gracefully shutdown where possible (VMs will receive an ACPI system_powerdown event) and be left in the shutdown state after the rolling restart has completed. Please allow for up to 1 hour after the stop action before restarting the affected VM instances. You are able to see the time of the stop action from the Action Log tab of the instance's page for the VM in the Nectar dashboard.
 
We apologise for any inconvenience this may cause.
 
Kind regards,
QRIScloud Support
