@jerry @pauliehedron All good. Shouldn't be an issue in my experience. The resolving server should have tried the next record (dino). Not sure why there is a resolution error for so many right now, but updating the Authority records to only include dino may be the only thing I could see interfering with resolution. the 1 hour TTL should only apply to records that are successfully retrieved, so the caching rules for a missing or error result are per-resolver
