IMHO, 6xx responses are globally authoritative in that the chance of using the same R-URI to perform a lookup somewhere else does not have any higher probability of success. 4xx response are repairable; if you can't get to the resource at one server, maybe another server can help. _______________________________________________ It's true that 6xx responses are globally authoritative, but what they are asserting is not that the *same* RURI in another location would produce the same result, but rather that the no success can be obtained by *any other fork of the same INVITE*. The problem with that is that various forks of an INVITE can have different RURIs, and the element that is attempting to be globally authoritative cannot know what those RURIs are, and so cannot be globally authoritative for all of them.
