Blocks

Status Page Block

API-backed

A complete public reliability section with regional health, customer-first incident updates, component evidence, planned maintenance, and verified subscriptions.

Reliability

Public status and subscriptions

This is a working customer section rather than a monitoring screenshot: change region, inspect component evidence, read live incident updates, open the public JSON feed, preview a targeted subscription, deliver confirmation, verify it, reload persisted state, and exercise validation or exact-revision conflicts through HTTP endpoints.

Review

What changed in this block

The earlier example compressed an internal three-column dashboard into a public page, placed summary counters before urgent customer impact, kept all data in local arrays, used DomNativeSelect, and treated subscription as an unverified toggle save. The reviewed version uses the impact-first communication model found in mature public status products while giving availability evidence a quieter, editorial layout.

  • The overall status and latest customer update appear before internal-looking metrics, with clear affected capability and region details.
  • DomSelect provides descriptive region choices, while DomStatusPill, DomAlert, DomDialog, DomCheckbox, and DomJsonViewer carry reusable interaction and feedback contracts.
  • Regional health is server-derived from component states, and each component opens lazy API evidence rather than relying on client-only arrays.
  • The subscription flow validates scope, freezes an exact preview, retains delivery evidence, requires confirmation, rejects bad codes, and produces an immutable activation receipt.
  • The page naturally reflows inside a desktop window, a narrow iframe, and a mobile viewport without turning into a scaled dashboard.

API

Working public reliability lifecycle

Method
Responsibility
GET
Read regional component health, active incidents, maintenance, history, and public catalogs.
GET
Load one component’s 30-day evidence and related customer events.
GET
Expose incident updates as a JSON Feed-compatible public stream.
POST
Validate email, region, components, and message types before sending anything.
POST
Commit an exact preview and retain provider delivery evidence for confirmation.
POST
Activate a pending subscription with version checks and an immutable receipt.
POST
Restore the deterministic reliability demo state.

Customization

Implementation notes

Customer language

Describe visible impact, affected regions, data safety, and the next update. Keep internal service names and speculative root causes in the incident workspace.

Subscription ownership

Confirmation, component preferences, unsubscribe tokens, rate limits, and delivery receipts belong on the server rather than in local UI state.

Production adapter

The demo retains process-local state. Replace it with monitoring adapters, durable incident records, signed feeds, queued notifications, and database-backed subscriber preferences.
