Derived from #6. The service should return a 503 Service Unavailable if it's temporary unavailable (e.g. due to scheduled maintenance). If this is the case, a common practice is to return a Retry-After response header (RFC7231, Section 7.1.3) with an indication on how long the service remains unavailable.
