The outage is the setting.
The reasoning is the story.

Postmortems often compress an investigation into a tidy answer. Root Cause Casebook keeps the difficult middle visible: initial assumptions, evidence sources, dead ends, turning points, recovery constraints, and the tests that changed the team’s mind.

Every public case is tied to an original incident report or vendor analysis and requires explicit editorial approval. Reported facts remain distinct from analyst synthesis, and missing evidence is not invented.
