Mumbai Coastline Concentrates India's Undersea Internet Cables, Raising Vulnerability

India's digital economy, projected to reach $1 trillion by 2025, relies heavily on a handful of submarine fibre optic cables that connect the nation to the global internet. The vast majority of these critical conduits, specifically 13 out of 18 intercontinental cables, make landfall in a highly concentrated area near Versova beach in Mumbai.

This geographical bottleneck represents a profound vulnerability. Any significant disruption, whether accidental or malicious, to this narrow coastal strip could severely impact India's international data flow, with cascading effects on finance, communication, and national security.

The concentration stems from a combination of historical infrastructure development and environmental factors. Mumbai's status as a major financial hub naturally attracted early cable investments, whilst the region's undersea geology, particularly the shallow continental shelf, offers favourable conditions for cable laying and maintenance.

However, this convenience has created a precarious situation. Experts warn that the absence of sufficient geographic diversification for these vital digital arteries leaves India exposed to substantial economic and strategic risks. Efforts to establish alternative landing sites and routes have been discussed but progress remains slow, leaving a considerable portion of India's digital future dependent on a very small, exposed stretch of coastline.
