A renewed geopolitical premium on undersea connectivity is reshaping how data centres are sited and compute is routed.

A renewed geopolitical premium on undersea connectivity is reshaping how data centres are sited and compute is routed.

The brief covers 31 newly signed subsea cables and six observable sovereign-interference events between 2024 and 2026.

We propose a "twin-coast plus twin-alliance" minimum-redundancy principle as a baseline siting constraint for compute clusters.

For operators, terrestrial, subsea and LEO links should be treated as sub-layers within a single redundancy budget.
