Cloud Giants Muscle Into Asia’s Undersea Network Plans

AUG East led by Singtel with AWS and Microsoft advances a new Asia cable for rising AI era demand, targeting Q3 2029 readiness

19 Nov 2025

Asia’s subsea network is set for a significant expansion with the AUG East cable, now under construction and scheduled to enter service in the third quarter of 2029. The system is expected to add new digital routes at a time when rapid growth in artificial intelligence and cloud computing is testing the capacity of older regional links. While the consortium has not released firm figures on bandwidth or latency, industry analysts consider the project an important addition to Asia’s dense cable landscape.

Singtel is leading the group behind the initiative, joined by AWS and Microsoft. The 8,900km system will connect Singapore and Japan, with branches to Malaysia, the Philippines, South Korea, Taiwan, Brunei and Indonesia. Analysts say traffic across these corridors is rising at its strongest pace in years, prompting operators to view the new line as a timely upgrade to the region’s digital backbone.

AUG East is notable for the active role played by major cloud providers. Their participation reflects a wider shift in how subsea projects are planned, as hyperscale platforms seek more direct influence over the infrastructure that carries their data. “Demand is rising so sharply that cloud companies want a seat at the planning table,” one analyst said, adding that cloud groups are pursuing predictable and scalable international capacity in several markets.

Much of Asia’s current inventory of cables predates the latest surge in AI-driven usage. Some routes face bottlenecks during peak periods, while others run through areas vulnerable to natural disruptions. By introducing new paths and distributing traffic over a broader geographic range, AUG East is expected to ease pressure on existing systems and improve network resilience.

Smaller carriers, however, have raised concerns that deeper cloud involvement could reshape competitive dynamics in the region. Despite these reservations, most analysts say the advantages of greater capacity and flexibility outweigh potential risks. They expect the project to stimulate wider investment in systems designed to handle the region’s persistent growth in data consumption.

With AI adoption spreading across sectors from retail to robotics, operators do not expect demand to slow. AUG East is positioned to play a central role in how businesses and households connect once the line becomes operational in 2029.
