Infrastructure domains

Each domain represents a combination of physical assets, digital systems, outsourced services, and human processes.

Energy supply

Includes:

  • Power generation (including the experimental “Geomantic Resonator” in the University)

  • Substations and switching nodes

  • Distribution networks (both above and below ground)

  • Smart meters and household connections

Building types: power_source (generating stations, one per district; the cascade root for all energy-dependent failures)

Energy underpins almost every other domain.

Water and sanitation

Includes:

  • Water treatment (the famous Ankh-Morpork Water Company)

  • Pumping stations

  • Distribution networks

  • Wastewater handling and processing

Building types: water_source (communal pumps and pumping stations: critical for low-wealth districts; failure here cascades to brewery, healthcare, and fire service)

Public tolerance for water disruption is extremely low.

Communications

Includes:

  • Semaphore relays and clacks towers

  • The new “Talking Drums” mobile network

  • Emergency communications

  • Coordination systems used by public services

Building types: clacks_tower (relay nodes, the backbone); communications_office (Grand Trunk Company, Talking Drums HQ, coordinate the network); media (Ankh-Morpork Times shapes narrative and acts as a detection mechanism); hackerspace (Scarlet Semaphore does informal resilience and vulnerability research)

Loss of communication amplifies every other incident.

Transport and movement

Includes:

  • Bridges (including the unreliable Brass Bridge)

  • Traffic control (watchmen on point duty, experimental automated gates)

  • Public transport coordination (horse-drawn omnibuses, canal barges)

  • Logistics routes to the docks and the Sto Plains

Building types: transport (bridges and major chokepoints: structural degradation hides; closure is immediate and isolating)

Transport failures have visible, immediate impact on daily life and business.

Public services

Includes:

  • Lady Sybil Free Hospital and other care facilities

  • City Watch and emergency services

  • Fire posts and emergency pump stations

  • Municipal administration (the Patrician’s Palace)

  • Enforcement and safety services (the Guilds, the Watch)

Building types: healthcare (hospitals: catastrophic sensitivity; failure is instantaneous trust collapse); security (Watch posts and Dept. of Silent Stability: very high sensitivity; absence enables cascading criminal interference); fire_service (fire posts: invisible failure until a fire; without them, workshop fires become district fires)

Failures here are politically sensitive and hard to recover from reputationally.

Commercial and industrial sites

Includes:

  • Food production and storage (the slaughterhouse district, the cheese caves)

  • Markets and retail (the Shambles, the Saturday Market)

  • Brewing and distribution

  • Finance and payments (the Royal Bank of Ankh-Morpork, the Guild of Merchants)

  • Workshops and small manufacturers

  • IT and data contractors

Building types: food_supply (markets and warehouses: just-in-time; shortages visible fast); brewery (single point of failure for the city’s beer supply; cultural and social cascade); workshop (artisan production: individually minor, collectively the industrial backbone; industrial fire risk); tech_business (Golem Trust, Purple Lantern: invisible until compromised; vendor monoculture risk)

Disruption here translates quickly into economic and political pressure.

Residential areas

Includes:

  • Homes and tenements

  • Apartment buildings (especially in the more respectable parts of the city)

  • Small businesses operating out of dwellings

  • Local utility connections

Building types: slum_dwelling (Shades, Cockbill Street: extreme sensitivity; no margin for error); middle_class_housing (Isle of Gods, Small Gods residences: high sensitivity; vocal and politically connected); civic_amenity (museums, theatres: low crisis priority but high cultural significance)

Residential impact is where abstract failures become personal.
