Hi Jason Hargrave,

You are experiencing health issues with your Azure App Service. When your app restarts due to unplanned events, the Azure Spring Apps instance will display a "degraded" status in the Resource Health section of the Azure portal.

• Check Azure Service Health by navigating to the Azure portal and selecting Service Health. Review any notifications regarding incidents or maintenance that might be impacting your app service.
• Check the Resource Health Status, navigate to the Azure portal and access the Resource Health section for your app service. This will provide the current health status and any recent events that may have affected your service.
• Review the Health History section, you can examine logs related to app crashes, health check failures, and platform/system issues. This will help determine whether the issue is caused by your application or the Azure infrastructure.
• Please investigate logs and metrics using Application Insights or Log Analytics to identify errors, high CPU or memory usage, and dependency failures.
• Make sure that health checks are properly configured and that auto-heal settings are enabled to automatically recover unhealthy instances. 
• Restarting your App Service Plan can refresh all instances and may resolve transient issues.
