Critical infrastructure guide
Service Continuity Planning
Keep priority infrastructure functions operating when normal arrangements are disrupted.
Systems note: infrastructure classifications, standards and responsibilities vary by country and operator. Use current local requirements for real decisions.
Why this matters
Keep priority infrastructure functions operating when normal arrangements are disrupted.
Core system ideas
Continuity plans identify essential services, minimum acceptable levels and resources needed to sustain them.
Alternative staffing, communications, suppliers and operating locations may be as important as backup equipment.
Plans need exercises and revision because dependencies and organizations change.
What to review
Useful reviews usually combine service criticality, dependencies, condition, capacity, maintenance, alternate arrangements, restoration time and clear ownership rather than relying on one isolated metric.
