Website resilience

Graceful failure — error pages, offline, redirects. Curated from the Website Specification — Resilience (CC BY 4.0).

Required

  • Custom error pages (404, 500) that return the correct HTTP status, explain what went wrong in plain language, and offer a way forward without leaking implementation details.

Recommended

  • Maintenance pages return HTTP 503 with a Retry-After header.
  • Graceful degradation: core content and primary navigation keep working when JavaScript fails.
  • Web app manifest (manifest.json) declaring name, icons, start URL, theme colour, display mode.
  • Monitor uptime from outside your own infrastructure; run a status page on a separate host.

Optional

  • Service worker serving a cached offline fallback page.
