Azure App Service hosts the web applications and APIs that customers and employees actually touch, which makes its incidents immediately visible - a healthy backend behind a failing App Service front end still looks like a full outage to the business. Problems usually appear as elevated 5xx rates or slow cold starts in one region rather than a global failure.
Elevated 502/503 rates for apps on a subset of scale units in one region
Slow or failed app restarts and deployments (control-plane impairment)
SSL/TLS or custom-domain binding issues after platform updates
Dependency failures - Storage or Entra ID incidents surfacing as App Service errors
