Summary
- Lancom now offers customers access to GNM-IX through its existing network.
- The arrangement uses a 100G connection in Sofia, Bulgaria.
- The development expands connectivity services rather than physical data centre capacity.
Lancom has expanded its telecommunications portfolio to offer customers in Greece access to GNM-IX, an international internet exchange, through a 100G network connection in Sofia, Bulgaria.
The arrangement allows customers to access the exchange’s services through Lancom’s network without establishing their own point of presence outside Greece. It provides additional options for exchanging traffic with international networks and content providers.
The company announced the service expansion on 22 October, identifying internet service providers, carriers, content delivery networks and enterprise customers among its potential users.
Lancom operates three data centres in Athens and Thessaloniki alongside telecommunications, cloud and cybersecurity services. International connectivity forms part of its ability to provide network access to customers using those facilities and related services.
GNM-IX operates an internet exchange platform through which participating networks can arrange direct traffic exchange. Peering agreements allow networks to exchange traffic at defined interconnection points, potentially reducing their dependence on alternative transit routes.
The availability of an exchange connection does not mean that every participant automatically exchanges traffic with every other network. Individual peering arrangements depend on the policies and commercial decisions of the operators involved.
Lancom says customers can access a wider ecosystem that includes major international networks such as Meta, Akamai, CDN77 and Hetzner Online. These are potential peering relationships through the exchange rather than confirmed individual connections for every customer.
The company’s physical connection to GNM-IX uses a 100G port in Sofia. This provides an interface into the exchange infrastructure, although the nominal port speed is not a guaranteed throughput figure for individual services.
Actual network performance will depend on the configuration of the customer’s service, the capacity available along the chosen path and the routing policies used by the connected networks.
International peering can form an important part of data centre connectivity. A facility may provide reliable local computing and storage systems while remaining dependent on external networks for access to customers, applications and other computing locations.
Having additional points of interconnection gives operators more choices when designing those routes. It can also support alternative traffic paths where the underlying connections and routing arrangements provide genuine independence.
However, adding an exchange service does not automatically establish improved network resilience. A useful assessment would require information about route diversity, upstream dependencies, available capacity and behaviour during network faults.
The commercial announcement is also distinct from the initial establishment of Lancom’s connection to GNM-IX. Exchange membership information indicates that Lancom joined during September 2026, before the current customer-facing service update.
The October development therefore concerns access to GNM-IX through Lancom’s telecommunications portfolio, not the completion of a newly installed connection during the month.
Greece’s position in the eastern Mediterranean creates demand for international network links serving local enterprises, service providers and digital infrastructure operators. The value of specific interconnection arrangements depends on the traffic destinations and connectivity requirements of each customer.
Lancom has not disclosed customer adoption figures, measured latency reductions or independently assessed improvements in service availability resulting from the arrangement.
The service nevertheless provides an additional option for Greek customers seeking international peering through an existing domestic provider, extending the network choices available without requiring them to establish and operate their own foreign infrastructure presence.
