Colt Technology Services added more high-bandwidth network routes to connect the U.S. East Coast to mainland Europe to meet surging demand for AI workloads.

The expansion provides Colt customers and partners with capacity on the Marea subsea cable stretching from Virginia Beach to Bilbao in Northern Spain. European customers can then connect to the infamous "data center alley" of Ashburn, Virginia, via New York, providing high-capacity routing options.

Users can leverage connectivity ranging from 100 Gb/s (100G) to 400G wave options between the two continents.

“As demand for high-performance, energy-efficient connectivity accelerates, businesses rely on Colt to deliver the scale, resilience, and innovation they need to lead in a rapidly evolving digital landscape," Colt COO Buddy Bayer proclaimed in a statement.

Colt’s continental network expansion comes amid apparent surging AI traffic loads and a subsequent need for secure, low-latency connections.

According to the provider, transatlantic subsea cables already carry 55% more data than transpacific routes, while global used bandwidth has tripled since 2020.

Colt wants its expanded transatlantic routing options to support the growing connectivity demand. Its presence in the U.S. now surpasses four cable landing stations on the East Coast, with on-network options across 10 transatlantic systems.

The firm has been steadily building out its infrastructure stack for some time, most recently tapping Nokia for its high-capacity optical shelves to reduce power consumption per bit for networks handling AI workloads.

Last summer, Colt showcased a proof-of-concept that would allow its users to define their preferred network route on a packet network, directly from its network-as-a-service (NaaS) platform.

The Smart Path feature sought to remove the need for traditional manual ordering processes, helping customers to better manage network performance through accelerated provisioning times.
