When deployment fails, App_Offline.htm is kept in the application directory and must be manually removed. This is documented but extremely difficult to diagnose. The web application just serves blank 503 page with no indication of the reason. Failed request tracing does not help:
Describe the solution you'd like
Indicate somewhere that the presence of App_Offline.htm is the reason for the 503 response. This could be a substatus code, error code, failed request tracing message and/or a response header or content.
