+### Shared clusters (default)
+All shared clusters in the following regions use availability zones. If your workspace is in one of these regions, Azure Monitor replicates your logs across the region-specific zones, as of January 2024.
+
+* Canada Central
+* France Central
+* North Europe
+* South Central US
+* Southeast Asia
+* UK South
+* West US 3
