Who is LINX - London Internet Exchange?
LINX - London Internet Exchange is a member-owned Internet exchange point that provides peering and interconnection services for networks operating in the United Kingdom and internationally.
- Neutral peering and interconnection fabric for ISPs, carriers, cloud providers, content networks, and enterprises (network interconnection)
- Multiple exchange locations and data center presence across the UK and selected international sites (network infrastructure)
- Private interconnect and closed user group options for controlled traffic exchange between defined participants (network connectivity)
- Route server and related BGP-based services to simplify multilateral peering (routing control)
- Support, monitoring, and member services for operational stability and Traffic Engineering (TE) (network operations)

More About LINX - London Internet Exchange
LINX - London Internet Exchange operates as a neutral Internet exchange point (IXP) through which networks such as Internet Service Providers (ISP), carriers, content delivery networks, hyperscale cloud platforms, and enterprise networks interconnect and exchange IP traffic. For enterprise and institutional stakeholders, LINX offers a way to reach a broad set of networks through a single technical and commercial relationship, rather than maintaining many discrete private network interconnects in each data center.
LINX interconnection services are based on Ethernet switching platforms and standard internet routing protocols, with Border Gateway Protocol (BGP) as the foundational control-plane technology for peering. Members connect physical or virtual ports in LINX-enabled data centers to access shared layer 2 fabrics, over which they establish BGP sessions either directly with other members (bilateral peering) or via LINX-operated route servers (multilateral peering). This arrangement supports IPv4 and IPv6 traffic exchange and allows networks to engineer routes based on business and technical policies.
Enterprises use LINX to improve network paths to cloud services, Software-as-a-Service (SaaS) providers, and content networks, and to manage transit costs by offloading traffic to settlement-free or cost-structured peering relationships. For carriers and service providers, LINX functions as a traffic aggregation and distribution hub, allowing them to connect to many counterparties through standardized interfaces and consistent operational procedures. The exchange’s presence across multiple carrier-neutral data centers adds location flexibility, so organizations can connect from existing colocation environments without relocating infrastructure.
Technically, LINX operates high-capacity, redundant switching infrastructures built around MPLS-capable and Ethernet-based platforms that support VLANs, jumbo frames, and various port speeds suited to different traffic volumes. Route server infrastructure supports communities and routing policy controls, which members use with BGP to manage announcements, selective peering, and TE. Monitoring and support services provide visibility into port utilization, latency within the exchange fabrics, and general platform status, which network operations teams rely on for capacity planning and incident response.
Within an enterprise IT and infrastructure directory, LINX fits into categories such as network interconnection, peering and transit optimization, carrier-neutral exchange services, and cloud and content connectivity enablement. It does not function as a general-purpose cloud, security, or application hosting provider; instead, its role is focused on IP traffic exchange at the network edge between independently operated autonomous systems. Organizations evaluating Wide Area Network (WAN) architecture, multi-cloud connectivity, or internet edge design can treat LINX as an option for regional and international peering in and from the UK and selected remote locations.
