GNM Expands European Backbone with New Optical Routes from Sweden to the Balkans

A major hardware and rack-level modernization at GNM’s Kista node finalizes the Frankfurt–Kista corridor upgrade, increasing available bandwidth, reducing energy consumption, and improving operational efficiency in Northern Europe.

Concurrently, a new dual-path DWDM route has been launched between Bratislava and Sofia, with one path via Serbia (Belgrade) and another via Romania. The routes converge in Sofia, establishing a resilient and scalable North–Southeast optical corridor.

“By connecting Northern and Southeastern Europe through diverse, high-capacity links, we’re strengthening the backbone for regional transit and future growth,” said Alex Surkov, Head of Development at GNM. “Sofia’s position as a regional hub makes it key for aggregating traffic from the Middle East, Turkey, and the Balkans“.

The expansion supports growing demand for low-latency, high-availability infrastructure across Europe, particularly from regional carriers, content networks, and platform providers.
