Geopolitics and Digital Sovereignty in Greenland#

Signe Ravn-Højgaard (Tænketanken Digital Infrastruktur)

• Why: An extreme-case stress test of resilience design: an entire national ecosystem hanging off two submarine cables with routing terminating abroad. It exposes failure modes (single-corridor dependence, no traffic localization) that softer versions exist in most networks.
• What: An examination of Greenland's structural dependence on U.S.-controlled infrastructure across multiple layers: two submarine cables plus limited satellite links, routing and traffic flows largely terminating outside Greenland, and minimal local traffic localization — and how that constrained path diversity intersects with heightened geopolitical attention. (from abstract only)
• How: Case analysis of connectivity topology and traffic flows (15-minute short talk).
• Where applicable: Greenland-specific, but the failure patterns — path diversity below the redundancy threshold, external hosting, no local traffic retention — generalize directly to any WAN resilience review. A good forcing function for asking "what is our two-cable equivalent?"
