Source: https://dnsdoctor.dev/.well-known/ard.json, this publisher's own file. Identifiers are reproduced exactly as published. Of the resources listed, 2 have been probed for reachability. "Answers" and "no response" describe only whether an endpoint replied when last probed: services go down and come back, and an entry is demoted rather than removed. None of this is a trust, quality or safety rating.
