Colt enables the digital transformation of businesses through its intelligent, purpose-built, cloud-integrated network, known as the Colt IQ Network.


Colt is the New Standard in high bandwidth network and voice services for enterprises and wholesale customers in Europe, Asia and North America’s largest business hubs. With a global reach but a deep local presence, Colt is big enough to deliver and small enough to care.


It connects over 850+ data centres around the globe, with over 27,500 on-net buildings and growing. Colt is also recognised as an innovator and pioneer in software defined networks (SDN) and network function virtualisation (NFV).

We deliver a consistent and predictable experience between Europe, Asia and North America over a common platform and technology, allowing businesses to address the challenges digitisation brings, by focusing on their business priorities, and accessing new and emerging markets.


You can rely on Colt, because we have been specialists in network and voice services for mid-to-large sized organisations and data intensive businesses for over two decades. We also specialise in improving performance for Capital Markets customers on a global scale.


Wherever you go, your network infrastructure will follow with the right fit commercials, management and service levels. You choose how your services are consumed, delivered and managed.
