title: AppFog - Error (JSON 503): <?xml version="1.0" encoding="u
body: <p>I'm trying to deploy a Rails app (2.3.8) on AppFog using the commands:</p>
  
  <pre><code>af login
  af update app_name
  </code></pre>
  
  <p>I'm using update because the app is already existing on AppFog. However, I keep getting this error:</p>
  
  <pre><code>Error (JSON 503): &lt;?xml version="1.0" encoding="u...
  </code></pre>
  
  <p>It happens after uploading the files. Running <code>af update</code> usually gives me that error. In fact, I've only ran that command successfully once in around a hundred times. I've tried deploying on different times around the clock, but no success. I've also tried using different servers of AppFog (US, EU, SG) but no luck either.</p>
  
  <p>Anyone else having the same issue? Does anyone know a workaround for this? Thanks a lot!</p>
