## What it is
A public status page lists the components of a service with their current state, announces scheduled maintenance and keeps a history of incidents with their updates. It is not internal monitoring: it reports what users experience, in their words, and it is read most on the days the service is down.

## Why it matters
Users and support staff check the page before opening tickets; partner teams and automated clients read it or its feed to decide whether to retry or to page their own people. A page that says "all systems operational" during an outage costs more trust than having no page.

## How to apply
- Host the page, its DNS and its domain with providers that share nothing with the service: different hosting, different CDN, ideally a different registrar. A page that goes down with the service is decoration.
- Choose components by what users can tell apart: web app, API, email delivery, payments; not internal cluster names. Keep the list short enough that every component has a distinct user-visible failure mode.
- Define the states (operational, degraded, partial outage, major outage, maintenance) in user terms and write the definitions down so two people post consistently.
- Grant posting rights to everyone on call and remove approval steps. The first update may say only "investigating reports of errors in X" and when the next update comes.
- Post on a fixed cadence during an incident even without news; silence reads as abandonment.
- Automate the obvious half: an external probe that fails for several minutes may flip a component to degraded automatically, with a person confirming or correcting. Do not automate "resolved"; a person confirms recovery from the user's side.
- Announce maintenance windows in advance with start, expected end and expected effect in a named time zone, and close them when the work is done.
- Keep incident history public with a link to the postmortem summary; it shows how the service handles failure.

## Pitfalls
Component states that reflect one region while users elsewhere are down. A "degraded" state used so often it means nothing. Editing or deleting history after the fact. Uptime percentages computed by the page provider from probes that do not match user experience. A page whose only reader is the team that writes it, because nobody linked it from the product and the error pages.
