Arelion has added several enterprise and wholesale customers to its Helsinki–Warsaw data corridor and provisioned multi-terabit capacity, expanding a network path through the Baltics for European traffic.
In its Oct. 19 update, the telecommunications carrier said the capacity is live. It did not identify the customers or give an exact capacity figure.
The corridor belongs to a ring linking Sweden and Finland with Estonia, Latvia, Lithuania and Poland. Arelion announced the corridor’s completion in October 2025 and said it combines its own infrastructure with fiber from regional partners. The company said the route bypasses Copenhagen and Stockholm, giving customers another path between the Baltics and Western Europe.
Arelion said its Baltic deployments now include IP Transit, Ethernet and wavelengths. It cited demand from financial services, cloud and hosting companies, and digital platforms, linking their capacity needs to AI and cloud workloads. Those demand and route benefits are the company’s claims; the update gives no customer-level traffic figures or measured performance results.
Henrik Almroth, Arelion’s sales director, said customers increasingly include the Baltics when planning their European networks.
A European Union project selection document names Arelion as coordinator of the Baltic Ring project under the second 2022 Connecting Europe Facility Digital call. It sets a maximum EU contribution of €1.74 million. That ceiling does not establish how much funding was paid.
Arelion said further deployments are underway but gave no timetable.
