title: Is there way to determine why Azure App Service restarted?
body: <p>I have a bunch of websites running on a single instance of Azure App Service, and they're all set to Always On. They all suddenly restarted at the same time, causing everything to go slow for a few minutes as everything hit a cold request. </p>
  
  <p>I would expect this if the service had moved me to a new host, but that didn't happen -- I'm still on the same hostname. </p>
  
  <p>CPU and memory usage were normal at the time of the restart, and I didn't initiate any deployments or anything like that. I don't see an obvious reason for the restart.</p>
  
  <p>Is there any logging anywhere that I can see to figure out <em>why</em> they all restarted? Or is this just a normal thing that App Service does from time to time?</p>
