 Before going over recommendations for achieving higher availability, you should understand the default availability and durability of managed disks.
 
-Managed disks are designed for 99.999% availability and provide at least 99.999999999% (11 9’s) of durability. With managed disks, your data is replicated three times. If one of the three copies becomes unavailable, Azure automatically spawns a new copy of the data in the background. This ensures the persistence of your data and high fault tolerance.

+Managed disks have two redundancy models, locally redundant storage (LRS) disks, and zone-redundant storage (ZRS) disks. The following diagram depicts how data is replicated with either model.
 
-Locally redundant storage (LRS) disks provide at least 99.999999999% (11 9's) of durability over a given year and zone-redundant storage (ZRS) disks provide at least 99.9999999999% (12 9's) of durability over a given year.

 A regional Virtual Machine Scale Set is a Virtual Machine Scale Set that has no explicitly defined availability zones. With regional virtual machine scale sets, VM resources are replicated across fault domains within the region they're deployed in to improve the resiliency and availability of applications and data. This configuration spreads VMs across fault domains by default but also provides the ability to assign fault domains on VM creation. See [this section](../virtual-machine-scale-sets/virtual-machine-scale-sets-use-availability-zones.md#regional) for details.
 
 Regional Virtual Machine Scale Sets don't protect against large-scale outages like a data center or region outage, and don't currently support Ultra Disks or Premium SSD v2 disks.
