Protecting Submarine Cables: Cyber and Physical Security

🔒 Submarine cables carry between 95% and 99% of global data traffic, yet recent breakages — notably ten in the Baltic Sea between 2022 and July 2025 — highlight persistent vulnerabilities. Private operators now control most capacity, and governments and vendors must address both physical threats such as fishing and anchors and increasingly sophisticated cyber risks. Major cloud vendors emphasize route diversity and redundancy while operators like Telxius combine burial, audits, AI/ML detection and continuity planning to protect service availability.

A Framework for Measuring Internet Resilience Nationwide

🔍 This post introduces a reproducible, data-driven framework to quantify Internet resilience, motivated by the July 8, 2022 Rogers outage that affected millions. It defines resilience as the ability of a national or regional ecosystem to maintain diverse, secure routing and rapidly recover from failures. The framework combines public sources (RouteViews, RIPE RIS, traceroutes, IXPs, submarine cable maps) and focuses on measurable metrics such as RPKI, ROV, IXP distribution, submarine cable diversity, AS path diversity, and impact-weighted assessments.
