Editorial contextDavid Lawrence and the DNS Answer That Outlived Its TTL, When a DNS answer reaches the end of its TTL, a recursive resolver normally discards or refreshes it. RFC 8767 allows a narrower choice during failure: preserve the expired copy for a bounded time, return it only after a real refresh attempt cannot produce usable data, and keep searching for the authoritative source. The old answer can carry continuity without inheriting authority.Medium confidence
