Build your core network backbone

Demand secure, high-performance, high-bandwidth connectivity

Modern bandwidth requirements are causing strain on traditional networks

With the growth of cloud and amount of data increasing exponentially every day, the quality and coverage of your high-capacity backbone network is more critical than ever, for you and for your customers.

Interconnection bandwidth alone is forecasted to grow at 45% CAGR globally, according to a recent report from Equinix, to reach 16,307 Terabits per second by 2023.

Relying on public internet to manage your vital collaboration tools can bring challenges with speed and reliability, impacting team performance. Your cloud tools and applications are only ever as good as the network which delivers them, and so companies are increasingly turning to dedicated networks and prioritised traffic to ensure smooth performance.

You need a connectivity partner who provides services wherever you need them, who can provide end-to-end service assurance and visibility, and who can offer added security where required.

Whether you are looking to transport high volumes of data between your key data centres, or require dedicated high-bandwidth connectivity, you need a partner that you can rely upon every second of every day.

Your challenges are our challenges. With nearly 30 years experience, we're investing not just in our network, but into the service and support that goes with it, to ensure that we're constantly exceeding your expectations.​
