Our highly available and secure network has breadth and depth across 3 continents, allowing us to support the technology and communication services on which our customer’s business depends. We are present in 28 countries in Europe, Asia plus the US and have agreements with providers in others so we can ensure total European coverage.

Our expanding, state of the art network seamlessly connects 47 metropolitan area networks, 205 cities and over 22.500 buildings. Customers of all sizes across various business sectors benefit from the services that our network supports with the industry’s highest standards in performance, latency and security.

Our network is continually growing and evolving. The scale, coverage and capability of a supplier’s network are key factors when looking to consolidate market share or move into new territories. The Colt network offers customers a single view of service activity and performance as well as a consistent user experience across geographies including 24/7 operational management. Our advanced infrastructure means our customers benefit from our flexible, responsive and reliable services day in, day out. Our stringent service level agreements (SLAs) for our on-net customers are one of the most demanding in the industry. We are expanding our network and we also have Off-Net initiatives designed to  improve both our footprint and services.

We own 22 data centres across Europe and manage a further 7 in the Asia-Pacific region. They are fully integrated into the Colt network, are continuously monitored and employ the latest technology to deliver cutting edge performance.

For many of our customers, we are their single, dedicated supplier of Data, Voice and Managed Services right across Europe and Asia. Using our network to deliver business grade services ensures our customers always receive the security and reliability they need to succeed in a fast moving marketplace.
