Certificates expire on a Saturday. DNS records drift without a deploy. Domains lapse because a card expired. Trace Warrior checks on a schedule and alerts by email or webhook the moment state changes — with 24-hour dedupe so one incident is one alert.
Days-remaining thresholds, chain validation, and protocol checks. Built for the 47-day certificate era.

Learn more →Anycast-aware change detection on A, AAAA, MX, NS, TXT, and CNAME records. Catches hijacks and fat-fingered edits alike.
