Infrastructure Dependency Atlas

Places where local populations are exposed to infrastructure decisions made outside their effective political control. Same thesis, different substrates.
U.S. Infrastructure

Domestic Dependencies

Documented cases where the geography of political accountability diverges from the geography of infrastructure control — across electricity, gas, water, and sewer systems.

16 cases 4 utility types 9 control layers
Hormuz Chokepoint

Energy Stress Under Disruption

Which countries have the least margin between disrupted supply and forced rationing. Stress bands based on import dependency, reserve depth, generation mix, and current grid condition.

12 countries 5 stress bands 7 dimensions Active crisis
Maritime Chokepoints

Narrow Transit Geometry

Five passages narrower than most rivers carry a third of global trade. Three are currently disrupted, constrained, or under elevated threat.

5 chokepoints 4 disruption levels 3 disrupted
Insurance

Insurance Dependency

Where insurer exit becomes a hidden governance layer over housing, mortgages, and community stability. The weather isn't the only hazard.

6 states 4 stress bands Active retreat
Fertilizer-to-Food

Agricultural Input Stress

Not every food crisis starts in a field. Some start in ammonia, shipping insurance, and one very narrow stretch of water.

12 countries 6 stress bands Active crisis
Water Basins

Water Basin Dependency

Where consumption happens is not where hydrological control sits. Compacts, aquifers, and governance weapons.

Grid Equipment

Transformer & Equipment Dependency

The invisible substrate. Long-lead transformers, single-vendor steel, and the physical limits of replacement.

7 cases 4 categories Active shortage
Subsea Cables

Subsea Cable Dependency

The cloud still has to come ashore somewhere. Landing concentration, corridor chokepoints, single-cable fragility, and 70 repair ships for the whole planet.

9 cases 6 categories Active threats
Cloud / CDN

Digital Infrastructure Dependency

Your local institution is operationally downstream of somebody else's region policy and billing model. Three providers, 62% of the market.
