Our network

Our managed network reaches more of Europe than any other. Customers of all sizes and working in every sector benefit from the fact that we offer direct-line connectivity to over 18,000 buildings in 39 major European cities. That last-mile fibre connection delivers the security and reliability our customers demand as they work to succeed in a fast moving marketplace.

For many of our customers, we are their single, dedicated supplier of Data, Voice and Managed Services right across Europe. We are present in 22 countries in Europe plus the US and have agreements with providers in others so we can ensure total European coverage.

Our advanced infrastructure means that you gain 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 and mean you can be sure that you’ll be able to make the most of our network 24/7, 365 days a year.

We have built 20 data centres across the continent and they are fully integrated into the Colt network to give you the certainty you need to work with confidence. They are continuously monitored, and employ the latest technology to deliver cutting edge performance in a sustainable way. For instance we use free air cooling in some of our data centres to cut power usage. The point is to deliver environmental benefits whilst offering an excellent service to our customers.
