availability testing

The availability testing tag covers Microsoft Azure Monitor changes affecting URL ping tests, including the planned retirement on September 30, 2026. The discussion focuses on practical monitoring migration rather than automatically replacing every free ping test with a paid Standard web test. Key considerations include inventorying existing endpoints, comparing costs based on test frequency and monitoring locations, preserving checks for business-critical public services, and consolidating lower-value coverage. The content also highlights a design limitation for private services that Standard web tests cannot reach, making this relevant to administrators planning endpoint monitoring, service availability checks, and budget-conscious migration strategies.
