A quick way to study this topic
- Hide the explanation and redraw these three anchors from memory.
- Explain the difference between the anchors in your own words.
- Apply the distinction to the worked example below. Check the full lesson for assumptions and exceptions.
- Recall it again tomorrow, then after a few days. A memory hint is a retrieval cue, not a replacement for understanding.

What this chapter explains
- Concepts and mechanisms
- Design, evidence and tradeoffs
Concepts and mechanisms
Facility design begins with business and safety requirements, environmental hazards, access needs and service dependencies. Location can expose systems to flooding, fire, utility interruption or access constraints. Physical boundaries, public and restricted areas, deliveries and emergency evacuation need a coherent design. Site selection should consider consequence and feasibility, not merely equipment space or rental cost.
Design, evidence and tradeoffs
Layer perimeter, building, room and equipment controls with approved roles and monitoring. Examine common utility, communications and staffing dependencies when claiming site independence. Safety and accessibility obligations constrain control choices; an access design must not create an unacceptable evacuation hazard. Integrate facilities, security and operations owners and validate maintenance and emergency conditions, not only ordinary entry.
Worked example
Two recovery sites use different buildings but share a flood zone and power dependency, limiting their independence for that scenario.
Check your understanding
Why can two physically separate sites still share one recovery risk?
Show explanation
The relevant environmental, utility, communication or operational dependency may affect both locations simultaneously.
