Azure Monitor customers may see issues while viewing Alert status for Service Health Events in the Alerts Blade in Azure Portal. This issue is limited to a subset of customers who have configured the Alert rule for Service Health events and the customer's subscription gets impacted by a given platform or service outage. When a subscription is impacted, we update the portal so that the customer is aware of the situation and can view this info under Activity Log, Service Health and Alerts Blade. Due to a bug this "alert information" is not available in Alerts and Service Health Blade however the customer receives email notifications and can view events in Activity Log or Service Health Blade. We already identified a fix and are in the process of final validation so that we can roll it out in all affected regions but due to the nature of the bug & dependency on many services we expect this to be resolved by Dec 15 across all regions. We apologize for any inconvenience it might have caused.
