Site Cutover & Takedown Host Checklist
Inventory every host, route, redirect and callback that serves your site before a move or takedown, as questions. Before you move a site to a new host or domain, switch repositories, or take a site down, build a read-only inventory of EVERY place that serves or references it, not just the one repository you are looking at. Greps your repo and config for DNS hints, CDN and edge routes, redirects, mirrors and second repos, sitemaps, canonical tags, hard-coded URLs, callback URLs, analytics properties and cache clues. Outputs an ordered runbook with per-host verification commands (you run them), rollback points, and a verified gone / verified moved / UNSURE table. Never executes changes or network calls and never invents a host; anything not found becomes a question.
