Microsoft-backed I-2SEA cable links India to Singapore for AI traffic is a business and technology story about AI-ready connectivity between India and Southeast Asia.
What changed
The core facts are: Lightstorm, Microsoft, Singtel and Tata Communications signed the I-2SEA agreement on July 1; the 3,600 km system runs from India’s east coast to Kuala Lumpur and Singapore, with NEC equipment and ASEAN Cableship construction; commercial service is planned for the fourth quarter of 2029; Lightstorm frames the cable as an extension of its SmartNet AI Fabric for data centers and GPU clusters.
Why it matters
The signal is that subsea bandwidth, GPU clusters and AI data-center corridors. The story is less about a single announcement than about how AI is moving into budgets, infrastructure, regulation and operating workflows.
What to watch
The next check is whether AI demand still justifies the route when the cable enters service in 2029.
