Elsewhere running MOQtail
10 other endpoints run the same implementation. Each is a separate deployment at its own version and configuration, so what one answers is not a claim about the others. All of them are run by the same operator as this one.

If something here is wrong, tell us — we keep what each result rests on, so a disputed one gets re-read rather than re-argued. We can also run this against endpoints that are not public.
