India’s Subsea Cable Crisis Exposed

India’s massive digital economy faces severe structural vulnerabilities due to a critical shortage of undersea internet infrastructure, exposing the nation to major connectivity disruptions.

The digital framework of the world’s largest democracy is operating on highly vulnerable infrastructure. Beneath soaring venture capital inflows and the artificial intelligence expansion sits a matrix of systemic discrepancies that illustrate India’s actual position and the hurdles it must face within the international undersea cable sector.

The corporate declarations have been immense. Google pledged $15 billion. Meta revealed a massive submarine line connecting to the subcontinent. Airtel activated 220 terabits per second of fresh data capacity. Visakhapatnam is positioned as the upcoming major data repository hub in Asia. The public narrative indicates India is rapidly expanding its underwater network connections as global technology conglomerates race to establish links.

This perspective is accurate but missing vital details. Beyond corporate financing announcements, the domestic network framework is restricted by deep operational challenges. Contradictions exist between national objectives and real-world deployment, regional positioning and regulatory oversight, and national independence and tech giant reliance.

This analysis examines the unresolved infrastructural challenges beneath Asia’s most prominent connectivity expansion.

PARADOX 01

18 percent of the world’s internet users. 1 percent of its cable landing stations

The nation represents roughly 18% of global web traffic, encompassing more than 900 million active subscriptions. It features the lowest mobile data tariffs globally, the second-ranked digital transaction ecosystem, and an IT export market yielding above $250 billion annually. By digital volume, the country operates as a global force.

Yet, regarding cable landing stations—the physical points where international fiber networks connect to domestic territory—the infrastructure remains severely limited. The country accounts for just 1% of global landing facilities. Singapore maintains 26 underwater lines across three hubs, while the United Kingdom displays far greater structural layout variance.

The regulatory demand for a tenfold rise in domestic landing infrastructure reflects basic requirements. The country’s highly affordable consumer data packages were established on a physical network foundation that cannot adequately accommodate the broader marketplace. The domestic revolution occurred before building the long-term infrastructure required to support it.

PARADOX 02

The East Coast has been dark for decades

The country possesses 7,500 kilometers of maritime borders, bordering highly critical global shipping lines including the Arabian Sea, the Bay of Bengal, and transit pathways toward the South China Sea. The regional position within the Indian Ocean remains highly strategic for international data routing.

Nevertheless, the eastern maritime border has remained underutilized for decades. The Bay of Bengal handles nearly 40% of international web traffic via the Strait of Malacca, yet lacks substantial domestic landing infrastructure. Outside of Chennai’s constrained facilities, international lines linking East Asia to Europe typically bypass domestic shores entirely.

The Visakhapatnam node, driven by Google’s regional infrastructure project and Airtel’s upcoming landing facility, marks a deliberate effort to alter this path. Three distinct fiber routes will converge at Visakhapatnam, linking to South Africa, Singapore, Australia, and Chennai. The local data center project plans to activate 1 GW of operational capacity by 2028, bringing the eastern coast into the global data transit network by 2026.

PARADOX 03

The cheapest internet in the world runs through the most dangerous waters

“60 percent of India’s internet traffic travels through the Red Sea. It has been disrupted twice in 18 months.”

Local citizens access mobile data at highly competitive rates, frequently below $0.10 per gigabyte. This pricing model stems from immense subscriber volumes, aggressive corporate rivalries, and the realization that primary data routes to European and Western hubs rely on the direct maritime path through the Suez Canal and Red Sea.

However, this commercial pathway traverses an active conflict zone. The Red Sea corridor has faced continuous instability since late 2023. In February 2024, four major underwater lines—SEACOM, AAE-1, EIG, and TGN—suffered physical damage in the sector, causing regional data degradations for months due to maritime safety risks delaying repair engineering.

A comparable multi-line disruption occurred in September 2025, damaging networks across South Asia and the Gulf, which triggered cloud architecture shortfalls confirmed by Microsoft Azure. With 60% of national international data flowing through this unstable space daily, local economic stability remains tied to a highly volatile global trade bottleneck.

PARADOX 04

India cannot fix its own cables

A critical element missing from public discourse regarding local telecommunication goals is that the nation does not possess a single domestic cable-repair vessel.

These specialized maritime units, vital for retrieving damaged oceanic fiber lines and executing repairs, are highly scarce globally, with only about 60 active ships managed by a narrow group of international industrial groups. Local line damages leave national network restoration entirely dependent on foreign corporate scheduling.

The crisis of February 2024 highlighted this vulnerability, as repair timelines extended across multiple months due to international fleet backlogs. The domestic market experienced extended throughput degradation while awaiting foreign vessel deployment.

This issue stems from evaluating international communication links as basic commercial utilities rather than critical national assets. Peer nations maintain dedicated domestic repair systems or shared maritime defense logistics. While regulatory frameworks focus on terminal diversification, the lack of sovereign repair ships remains largely unaddressed.

PARADOX 05

The southern route is a geopolitical asset India hasn’t claimed

The emerging network architecture entering Visakhapatnam, alongside alternative oceanic routes avoiding the Suez Canal by routing past the Cape of Good Hope, forms a highly strategic southern data transit corridor. These lines link European, African, and Asia-Pacific hubs entirely outside traditional Middle Eastern maritime bottlenecks.

The country occupies the central geographic nexus of this southern network corridor. Fiber routes running between southern Africa and Southeast Asian hubs achieve optimal efficiency by connecting locally to route regional data packets.

As traditional Red Sea paths face ongoing security challenges, alternative southern data routing will command premium valuations from international cloud providers, enterprise networks, and sovereign entities requiring continuous data integrity.

Future Outlook

The shifting dynamics of global data routing present an opportunity for India to transition into a primary data transit hub. Overcoming current infrastructural deficits requires significant capital allocation toward sovereign repair fleets and regulatory streamlining. If the scheduled infrastructure rollouts through 2028 succeed, the nation could secure its digital borders while transforming into a central anchor for data traffic across the Indian Ocean.

FAQs

Why does India have so few cable landing stations despite its huge internet user base?

India’s digital expansion focused heavily on mobile networks and consumer data pricing rather than foundational international infrastructure. This created a mismatch where 18% of global internet users rely on just 1% of the world’s cable landing stations.

How do Red Sea conflicts affect internet speeds in India?

Approximately 60% of international data traffic from the country passes through the Red Sea. Physical cuts to underwater cables in this zone disrupt financial networks and cloud services, causing notable latency issues and service degradations.

Why is the lack of domestic cable repair ships a national security risk?

The nation owns 0 cable repair ships, leaving it entirely dependent on a limited global fleet of roughly 60 vessels. When critical subsea infrastructure breaks, the country must wait months for foreign-controlled ships, leaving its international connectivity vulnerable.

What is the strategic value of the new Visakhapatnam data hub?

The Visakhapatnam gateway provides an alternative data path on the east coast, breaking the long-standing dependency on western routes. The hub will connect directly to Africa and Southeast Asia, aiming to deliver 1 GW of data center capacity by 2028.
