Chokepoint Monitoring Tools
Direct answer: PortWatch counts transits; it does not tell you what else changed. World Monitor fuses its 13 chokepoints with conflict events, aviation disruption, market moves, and climate hazards, so a chokepoint slowdown can be read next to the cable cut, the airspace closure, and the freight spike in one view.
