Cable landing stations are above-ground buildings with commercial security guarding national backbone access

Submarine cables terminate at cable landing stations -- typically unremarkable buildings on coastlines protected by commercial security guards and chain-link fences. These stations are where fiber transitions from undersea to terrestrial networks, making them single points of failure for entire regions. An attacker with a truck bomb could sever a nation's international connectivity at the physical layer. Most landing stations are in publicly known locations (visible on Google Maps) with no military-grade perimeter security. This persists because cable landing stations were built decades ago when physical attack on telecom infrastructure was not a considered threat, and retrofitting hardened facilities at every coastal landing point would cost billions that no commercial operator will spend.
