Today we are announcing that Always Serve for Azure Traffic Manager (ATM) is now available in public preview. You can disable endpoint health checks from an ATM profile and always serve traffic to that given endpoint. You can also now choose to use 3rd party health check tools to determine endpoint health, and ATM native health checks can be disabled, allowing flexible health check setups.
To enable AlwaysServe, you can use the Azure Portal (must include URL parameters included in this Hyperlink). You can also use he API version “2022-04-01-preview” and Azure PowerShell to enable this feature.
For more information on how to enable AlwaysServe, please refer to documentation.
