Network Redundancy & Design

Single Point of Failure

English

Overview

A non-redundant point whose failure would halt the entire system.

Details

A point lacking redundancy, whose single failure would cause an outage of the entire service. It's a target that should be eliminated by design. A common oversight is two paths that were meant to be redundant actually sharing the same power feed or the same conduit, failing together anyway -- truly eliminating a single point of failure requires checking for physical independence, not just logical redundancy.
