title: Azure - HTTP Server Errors from FrontEnd only detected
body: <p>I am trying to analyze below Azure observation when checked under &quot;Diagnose and Solve Problems&quot; feature - Web App Down. Azure SLA is 99.99% but it shows organic SLA - 99.98%. My App Service Plan is S1 and having only one application. Application is limited to business client but publicly hosted.</p>
  <p>client has not raised any concern about web app down. but below observation shows site was down as it is listed under Web App Down feature.  I see this observation daily. How do I interpret this?</p>
