Fix App Insights monitoring of an App Service so it does not have false negatives from some of 5 regions while the app remains up and health
Fix your networking problem. Monitoring an App Service in US West from US East, US South Central, US North Central and US West. I started getting failures in part of the regions in January 2020. App Insights has problems and it is absolutely unacceptable performance. See support Case 120021121007484 and talk to Jose Pablo Martínez

This is about how App Insights is handling the "transient" network issues in the Availability tests feature.
The documentation states:
"We strongly recommend testing from multiple locations with a minimum of five locations. This is to prevent false alarms that may result from transient issues with a specific location. In addition we have found that the optimal configuration is to have the number of test locations be equal to the alert location threshold + 2."
Kevin's concern is why should we be expecting transient issues in Azure. We know this is by design but he is looking for improvements on this area.
