## TL;DR

DNS records and propagation state help agents distinguish application outages from name-resolution and routing problems.

## Core Explanation

Agents diagnosing availability issues need DNS evidence before changing services. A missing A record, stale CNAME, misrouted MX record, wrong TXT value, or cached resolver response can make healthy infrastructure appear broken.

Good automation should inspect the record type, zone, authoritative provider, TTL, DNSSEC status, and observed resolver answers. It should also avoid assuming that a recent DNS edit is globally visible immediately.
