For the full value list and how the codes nest, use the [complete event taxonomy](/reference/taxonomy-complete). Energy, transport, supply chain, communications, and water infrastructure events, including strategic buildout milestones Filter with `GET /api/v2/events?family=cameoplus&cameoplus_domain=INFRASTRUCTURE`, or on a specific `subcategory` code below. Every code in this domain starts `IN`. Goldstein does not apply to this domain — see the [domain index](/reference/codes-domains). **How the metrics read in this domain.** magnitude uses the hazard severity tier for a realized disruption and the impact tier for a project; systemic\_importance is usually the decisive metric, since infrastructure is where irreplaceability is genuinely high ### `IN01` **ENERGY INFRASTRUCTURE EVENT** A discrete event involving energy production, transmission, distribution, or storage: major power grid failure or blackout affecting large populations, pipeline explosion or rupture causing supply disruption, refinery explosion or unplanned shutdown affecting regional fuel supply, LNG terminal outage, nuclear power plant emergency shutdown, major renewable energy facility failure, deliberate energy supply cut (gas pipeline closure by a state actor), or commissioning/opening/major capacity expansion of a strategically significant grid, pipeline, terminal, nuclear, hydro, or public-utility energy asset. **Also covers** * pipeline explosion/completion * refinery outage * power grid failure/milestone * nuclear incident/startup * Cyber operations against operational technology (power grid control systems, water treatment SCADA, port systems) producing physical disruption → IN01/IN06 as appropriate, with cybersecurity noted. **Does not cover** * If a hurricane causes a power grid failure, code the hurricane as EN02 and the grid failure as IN01 only if it is independently significant and treated as such in the articles. ### `IN02` **TRANSPORT DISRUPTION** A discrete disruption to major transport infrastructure, or a major new transport-system milestone: port closure or blockage affecting significant trade volumes, critical bridge collapse or closure disrupting arterial routes, major railway system failure or derailment affecting national/international freight, aviation system outage affecting air traffic control, significant canal or waterway blockage, opening or commissioning of a strategic port, bridge, rail corridor, airport terminal, or canal expansion that materially changes system capacity. **Also covers** * port closure * canal blockage * shipping lane attack * bridge collapse * rail failure * also strategic openings ### `IN03` **SUPPLY CHAIN DISRUPTION** A discrete event causing a significant disruption to the movement of critical goods: export ban or sudden halt of critical commodity flow (microchips, rare earths, grain, fertilizer, medical supplies), major logistics hub failure (port fire, warehouse explosion), critical chokepoint closure beyond normal transport disruption, coordinated disruption of a just-in-time supply network. Distinguished from IN02 (physical infrastructure) by focus on the commodity flow rather than the transport asset itself. **Also covers** * semiconductor shortage * critical material export halt * chokepoint disruption * GEOPOLITICAL SUPPLY EVENTS: deliberate export bans or supply cut-offs by state actors (e.g., gas pipeline shut-off as political tool) → IN03 (supply chain) if the effect is primarily a commodity flow disruption, or IN05 (sabotage) if the mechanism is physical destruction. ### `IN04` **COMMUNICATIONS INFRASTRUCTURE** A discrete disruption to communications or information infrastructure, or a strategic backbone milestone: submarine telecommunications cable cut or failure, major cloud infrastructure outage affecting widespread services, national or regional internet outage or shutdown, satellite system failure affecting GPS or communications, major telecom network failure, commissioning of a strategic submarine cable, backbone network, landing station, or nationally significant telecom backbone upgrade. **Also covers** * undersea cable cut/activation * telecom outage * internet exchange disruption * backbone activation ### `IN05` **DELIBERATE INFRASTRUCTURE SABOTAGE** A discrete act of deliberate destruction or sabotage of critical infrastructure: confirmed pipeline sabotage, deliberate power grid attack, port blockade, confirmed bridge demolition for strategic effect, deliberate supply route interdiction. Distinguished from IN01/IN02 by the presence of confirmed deliberate human intent to disrupt. The sabotage itself — not just its effects — is the primary event. **Also covers** * confirmed attack/sabotage of energy, transport, comms, water systems * GEOPOLITICAL SUPPLY EVENTS: deliberate export bans or supply cut-offs by state actors (e.g., gas pipeline shut-off as political tool) → IN03 (supply chain) if the effect is primarily a commodity flow disruption, or IN05 (sabotage) if the mechanism is physical destruction. **Does not cover** * Do not code as IN05 based solely on suspicion — use the most specific non-deliberate code (IN01–IN04) and note suspicion of sabotage in the notes field. ### `IN06` **WATER INFRASTRUCTURE EVENT** A discrete event involving water supply or hydraulic infrastructure: dam failure or emergency release causing downstream flooding, major water treatment system failure affecting large urban populations, deliberate dam destruction, aqueduct or water pipeline rupture causing significant supply disruption, major irrigation system failure during critical agricultural period. **Also covers** * dam failure/breach * desalination plant outage * municipal water supply collapse * major aqueduct failure * Cyber operations against operational technology (power grid control systems, water treatment SCADA, port systems) producing physical disruption → IN01/IN06 as appropriate, with cybersecurity noted.
