Submarine Cable Criticality
Which cables matter most, and which ones are most likely to break due to geophysical events? We layer geological hazard data on top of existing cable network maps to find the spots where risk concentrates.
The project is organised around four connected workstreams. Each produces both technical research and policy-facing outputs.

We want to know where a website actually lives, not just where its domain says it lives. We do that by measuring how quickly the site responds from different places around the world at the same time. If a site loads fast from Sydney and slow from Tokyo, odds are it sits somewhere in Australia.
This area builds on top of the measurement infrastructure the project depends on and translates technical findings into actionable recommendations for governments, network operators, and emergency services. Our goal is to deploy measurement probes where they do not currently exist, explore portable infrastructure for disaster scenarios, and develop policy guidance based on the evidence we've collected across our work.
This workstream maps where critical services in the South Pacific are actually hosted, and what happens when the paths to those services break. We classify domains by disaster-scenario priority - emergency services, transport, government, finance, media, and utilities - and identify hidden dependencies on CDNs, DNS providers, cloud hosting, and offshore infrastructure.
