For a single VM with mixed disk types, the lowest disk-type SLA applies. VMs sharing the same Shared Disk are treated like single-instance VMs. Azure SLAs are published only inside the consolidated Microsoft Online Services SLA document (monthly editions; the September 2026 edition was current on 2026-09-23).
