Why does Azure give me an intermittent Error 503. The service is unavailable?

Question

I have an Azure service that has been running for a long period of time. It builds a word or powerpoint document based on arguments in the request and returns a uri to the build document. This is access via a visualforce page, when you click a button, it calls the service and displays a link to the document that has just been built. Simple.

All of a sudden, I get an apparently random 503 Service Unavailable error. Sometimes I click the button, no problem. Other times a 503 error. Each time the button triggers exactly the same request. Does anyone know why this might be happening?

Apparently doing the same thing over and over again and expecting a different result, is not insanity!

Thanks for taking the time to read this.

Try to simply redeploy the cloud services to Azure which might solve your error. Whatever 'reboot' is necessary after deployment will rectify whatever the problem was. All I can suggest is that you try the same thing if you are getting intermittent 503 errors.
