Availability, content, DNS and registration are independent evidence layers. NXDOMAIN, an unreachable origin or missing content alone does not prove registrar action. A registrar or provider is credited only when a direct technical marker identifies that actor. Report causality is shown separately.
This timeline displays historical security and status checkpoints observed by the PhishDestroy automated monitoring network. It records domain lifecycle updates, scanner changes, and threat telemetry over time.
