single point of failure
Single points of failure (SPOFs) are aspects or parts of a system which, when they fail, cause crucial parts of (or the entire) system to fail. SPOFs are an important thing to take into account when designing software or creating a protocol.
- Websites that only offer Twitter as authentication provider will fail 100% of time to allow users access if Twitter is down
- All IndieWeb sites which rely on Bridgy to backfeed and POSSE, will not receive or send webmentions should Bridgy be down
- All users on a hosted instance of Mastodon or Diaspora will lose all services if that instance goes down
