This isn't Azure-specific. ASP.NET Web Applications run in w3wp.exe and can be killed and recycled by IIS at any time, without warning. The first request after a kill will cause Application_Start to be invoked again.

Depending on how active your website is, IIS may kill your website after a period of inactivity (to free-up memory), on the next request to your site IIS will relaunch the application and call Application_Start.

There are also circumstances where Application_Start will be called more than once for a single application initialization, though this is usually due to a misconfiguration:
