We will be upgrading the hypervisor kernel in our Sydney cluster to address CVE-2026-53359.

During the maintenance window, all virtual machines without AMD SEV-SNP enabled will be live migrated, and no downtime is expected.

VMs with AMD SEV-SNP enabled cannot be live migrated and will be rebooted during the maintenance.
