Serving Stale Data to Improve DNS Resiliency
Abstract
This draft defines a method (serve-stale) for recursive resolvers to use stale DNS data to avoid outages when authoritative nameservers cannot be reached to refresh expired data. It updates the definition of TTL from [RFC1034], [RFC1035], and [RFC2181] to make it clear that data can be kept in the cache beyond the TTL expiry and used for responses when a refreshed answer is not readily available. One of the motivations for serve-stale is to make the DNS more resilient to DoS attacks, and thereby make them less attractive as an attack vector.

“To our knowledge, Continnum is the first system to use TTL to regulate LLM KV cache as a function of predicted toolcall durations, scheduling-side delay propagation, and workload pattern.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
