Abstract
Suspected sabotage to submarine communication cables (SCCs) across the world has raised questions about the resilience of these systems. Data communication networks typically use a network approach, which spreads the networks’ capacity across diverse routes to provide redundancy. This study takes a risk mitigation and resilience perspective by investigating the information needed to support proactive rerouting decision-making. This study reveals that appropriate situational awareness is dependent on specific, real-time information about hazards and threats to the cable in question. For an operator of an SCC, such a contribution is not possible without being interpreted as an integral stakeholder in defence.
