Summary

The BCS East-West Interlink submarine cable and the C-Lion1 submarine cable, both connecting countries in Northern Europe to each other, were damaged recently, but surprisingly, there was little-to-no impact on Internet connectivity in the affected countries, Lithuania and Sweden, Finland, and Germany. The significant redundancy and resilience of Internet infrastructure in Europe played a crucial role in minimizing disruptions. Multiple terrestrial fiber connections between neighboring countries also contributed to this resilience. In contrast, cable cuts often cause significant disruptions to Internet connectivity elsewhere, particularly when they represent a concentrated point of vulnerability for an individual network provider, city/state, or country. Building redundant and resilient network architecture is a best practice to mitigate these disruptions.
