The expansion marks the latest phase of Colt’s global network investment and includes a new transpacific subsea route linking the US and Japan. The move strengthens Colt’s position beyond Europe, elevating it from the largest B2B fibre provider in the region to one of the most significant global players in digital infrastructure.

The new routes are designed to support customers’ international growth strategies, with financial services firms, content providers, neocloud companies and hyperscalers expected to be among the first to benefit. Enhanced connectivity will provide secure, high-performance backup and routing options for mission-critical applications, improving resilience across increasingly congested transpacific corridors.

The announcement follows recent investment in routes connecting the US East Coast to Europe, as Colt responds to surging traffic volumes driven by AI workloads. Increasing congestion across key global routes has led to latency, delays and service disruption, creating operational and financial challenges for enterprises.

As part of the initiative, Colt will deploy a new backbone route via the Juno Subsea Cable System, one of the most advanced subsea cable systems, connecting Tokyo to Los Angeles. The company will also integrate its terrestrial networks in both countries, offering customers greater diversity, bandwidth and resilience, alongside expanded on-net capabilities across major Tokyo data centre hubs.

Buddy Bayer, chief operating officer, Colt Technology Services said, “The world’s economies run on digital infrastructure, but there will come a point when existing capacity across some routes isn’t enough. This risks disrupting or even reversing the progress countries have made in connecting markets, organisations and societies.”

He continues, “At Colt, we have a deep commitment to solving problems for our customers so they can grow and scale. This investment in our digital infrastructure connecting the US West Coast to Tokyo, Japan not only solves the capacity problem for our customers – it’s a gateway to global growth”.

Spanning approximately 11,700km across the Pacific, the Juno system connects key landing points in Japan and the US and has been in service since May 2025.
