Dedicated leased lines explained

  • A leased line connection is typically a dedicated point-to-point internet link for commercial use. Leased lines provide a private, fixed-bandwidth, low latency data link exclusively for your business’s use.

    Unlike shared services such as standard broadband, a leased line does not have traffic contending for bandwidth, ensuring consistent high speeds and reliability. For more information see our article on what are leased lines?

  • The cost of leased line varies depending on your specific requirements. Use our request a quote functionality on this page to request a quote in less than 30 seconds, and receive a price within 48 hours.

  • By facilitating state of the art technology we can offer symmetrical leased line internet bandwidths from 1Gbps up to 10Gbps as standard.

    We are also able to upgrade your internet leased line up to 1Gbps anytime without physical changes (with virtual router when available).

    Our 100Gbps backbone has low utilisation levels and is being upgraded constantly. Colt runs a significant peering infrastructure with more than 400Gbps of public and private peering, attends 20 public internet exchanges and exchanges traffic with hundreds of networks directly.

  • On Demand combines Colt’s extensive IP peering with the flexibility and scalability enabled by software defined networking (SDN) automation. Benefit from real-time service provisioning, modify, schedule & scale your bandwidth and commitments in real time and choose from long-term fixed contractors, or per hour billing with no commitment.

  • Design your ideal business leased line service by cherry picking from a range of additional leased line service add-ons such as managed router, domain registration, IPV6, BGP, usage based billing, domain hosting and security options such as DDoS protection.

    We also have a sophisticated range of services to increase service availability to up to 99.99%.

  • IP Guardian will automatically filter DDoS attacks within seconds and without the necessity for human intervention, rerouting or tunnelling. IP Guardian can protect all leased line users regardless of the type or number of IP addresses used.

  • Colt Cloud Prioritisation is a feature now available for all new and existing Colt leased line for business customers. It provides guaranteed performance for Microsoft Office 365 services via the public Internet.

    Microsoft traffic can be prioritised over standard Internet traffic on the customers router and the Colt Edge Router. The service also features a high performance direct peering infrastructure between Colt and Microsoft in 21 cities across Europe and Asia.

  • Colt IP Access is the original name for our dedicated internet access / leased line offering. As detailed above, this is a high-performance business internet access solution, known for its resilience and suitability for business-grade needs.

    We can provide up to 100Gbps speed across a global network that includes extensive coverage in Europe, Asia, and North America.
