There are many possible responses, depending on why the UAS is unable to process the request. 503 is suitable if the UAS cannot process the request because it is overloaded or being maintained. > - What context 6xx failures occurs and who will be originating those > failure response.? 6xx responses should never be used. A 6xx response causes the failure to be propagated immediately to the UAC, without trying any alternative forks. But it is impossible for the UAS to know what URI the UAC originally addressed, and thus the UAS cannot vouch that no alternative fork could satisfy the UAC's request.
