Deployment Checklist
- Verify DNS delegation before requesting certificates.
- Prefer boring defaults until a baseline is measured.
- Keep one clean rollback path for every service change.
This small site collects deployment notes, protocol references, and plain-language reminders for keeping infrastructure tidy, measurable, and easy to revisit later.
Lightweight public surfaces matter. Health checks, certificate renewal, and clean listener ownership are easier to debug than one-shot scripts that hide state.
