Shared fate caps availability

Worked examples, recomputed

Every number the mechanisms quote for this relationship is recomputed from it, so none of them disagrees with it.

• three independent replicas at 99.9% → 10⁻⁹, but a shared 99.9% store caps the system at 99.9%

Where it appears

Each mechanism states it in its own names. The general symbol each name stands for is shown with it.

• Emergent Failure Dynamics

  What happens when nothing is broken, every component is healthy, and the system's own response to stress makes the stress worse?

  $$A_{\text{system}}\le A_{\text{shared}}$$
