Service overview

The Colt Ethernet Line/Hub & Spoke are point-to-multipoint enterprise network services that have the reliability and high quality of a leased line as well as the flexibility and cost effectiveness of an ethernet line. This connectivity solution for cloud, data centres and enterprise networks boasts high cost-effectiveness with a proven track record in both Europe and Japan.



The same Colt services that both foreign and domestic financial institutions depend on for missioncritical connectivity are now available in Singapore. On top of that, service availability, incident recovery, packet delivery, and service delivery are SLA-guaranteed, and our service conforms to MEF2.0 standards.

Low cost

We operate our own global network with metro area networks in 49 cities in Europe and Asia. We aim to lower customer costs by making use of our highly experienced global operations team and the latest SDN supported equipment, as well as reducing operating costs through economy of scale.

Great flexibility
