 Use [private endpoints](../../private-link/private-endpoint-overview.md) for Managed Prometheus and your Azure Monitor workspace to allow clients on a virtual network (VNet) to securely query data over a [Private Link](../../private-link/private-link-overview.md). The private endpoint uses a separate IP address within the VNet address space of your Azure Monitor workspace resource. Network traffic between the clients on the VNet and the workspace resource traverses the VNet and a private link on the Microsoft backbone network, eliminating exposure from the public internet.
 
+> [!NOTE]
+> Private Link functionality for Managed Prometheus and the Azure Monitor workspace is currently _unavailable_ in the following regions: Australia Southeast, Canada Central, East Asia, Norway East, South Africa North, UAE North, or West Central US. We expect this functionality to become available by early June 2023. All other regions where Managed Prometheus and the Azure Monitor workspace are available have full support for Private Link.

 > [!NOTE]
 > If you are using Azure Managed Grafana to query your data, please configure a [Managed Private Endpoint](https://aka.ms/ags/mpe) to ensure the queries from Managed Grafana into your Azure Monitor workspace use the Microsoft backbone network without going through the internet.

 Using private endpoints for your workspace enables you to:
 
 - Secure your workspace by configuring the public access network setting to block all connections on the public query endpoint for the workspace.
