"Fibre Is Out of Stock Across the Globe" - Why Vizag Is Becoming India's Third Digital Gateway

Source The Hindu, Google Cloud, Submarine Networks

"Fibre itself is out of stock across the globe," Lightstorm CEO Amajit Gupta told The Hindu - including from Indian manufacturers, with even the raw material running short. That single supply-chain complaint is the clearest sign yet of how fast Google and Microsoft are racing to build India a new digital coastline.

Summary

Google and Microsoft are building new subsea cable landing stations in Visakhapatnam and Machilipatnam, Andhra Pradesh, making it India's third international digital gateway after Mumbai and Chennai. The push is driven by AI data centre buildout and a deliberate move away from ageing, congested cables on India's existing coasts.

WHY IN NEWS FOR UPSC & STATE PCS

Google's America-India Connect system and a Microsoft-backed consortium building the 3,600 km India-Southeast Asia (I-2SEA) cable will both land on Andhra Pradesh's coast, alongside Google's new AI data centre complex in Visakhapatnam. Executives cited both AI infrastructure demand and geopolitical risk in West Asia as reasons for diversifying away from Mumbai and Chennai, where existing cables are 8 to 15 years old and running out of spare capacity.

A Third Coastline: What "Digital Chokepoint Resilience" Actually Means

Here's what's actually happening on Andhra Pradesh's coast: two of the world's largest tech companies are laying physical cables under the ocean floor and the reason has almost nothing to do with Andhra Pradesh itself and almost everything to do with what could go wrong somewhere else entirely.

India's connection to the global internet runs through a small number of physical points where undersea cables come ashore - Mumbai on the west coast, Chennai on the east. Nearly all of India's international data, from a WhatsApp message to a cloud server request, funnels through these two locations.

That concentration is a chokepoint: damage, congestion or disruption at either site has outsized consequences for the whole country's connectivity. Lightstorm CEO Amajit Gupta put the underlying problem plainly - the existing east-coast cables are "8, 10, 12, 15 years old," full of capacity and "rapidly running into end of life." The fix Google and Microsoft are building is not a government resilience programme - it is private infrastructure investment following AI compute demand.

Google's America-India Connect system and a Microsoft-backed consortium's I-2SEA cable will both land in Andhra Pradesh, specifically because Google is simultaneously building a large AI data centre complex in Visakhapatnam focused on "inference"

  • the stage where a trained AI model actually answers real queries, as opposed to the much more power-hungry process of training the model in the first place. A data centre that size needs enormous, low-latency bandwidth to the rest of the world and building that bandwidth on a new coastline solves two problems at once: it feeds the data centre and it gives India a genuinely separate physical route in case Mumbai or Chennai's cables are ever cut or overloaded. Gupta was explicit that geopolitics is part of the calculation too. With tensions affecting shipping and infrastructure in West Asia, companies are asking whether they can "flush the traffic out to the eastern coast of India" for an alternate path if a primary route is compromised. That is de-risking logic, not goodwill - Google and Microsoft need this redundancy for their own global networks and India's new gateway is a byproduct of that need, not its purpose. The exam-relevant point is who is actually building India's digital chokepoint resilience here. It is not a government cable-diversification scheme - it is private capital chasing AI infrastructure demand, with national resilience arriving as a side effect. Vizag becomes India's third subsea gateway not because a ministry decided India needed one, but because two hyperscalers needed a new coastline for their own reasons and India's connectivity map changes as a consequence.

Quick Facts

Key numbers & takeaways — revise these first

  • Most of India's international internet traffic currently passes through submarine cables landing in Mumbai and Chennai.

  • The new I-2SEA cable system will connect India with Singapore and Malaysia and is targeted for service by Q4 2029.

  • Visakhapatnam is being developed as India's third major international subsea digital gateway.
