RETN launches a new backbone route through Romania, strengthening digital connectivity between the Balkans, Moldova and Ukraine

International backbone operator RETN has announced the launch of a new end-to-end backbone route connecting Drobeta, Bucharest, Iași and Chișinău. The new route forms a continuous physical infrastructure corridor across Romania and into Moldova, offering an additional alternative to existing regional IP transit corridors in Eastern Europe.

The project is part of RETN’s broader strategy to strengthen its optical network across Central and Eastern Europe. By linking Romania and Moldova with RETN’s existing Balkan corridor between Budapest, Timișoara and Sofia, the company is creating a new geographic route for digital traffic between the Balkans, Moldova, Ukraine and the wider Central and Eastern European region.

For Ukraine, the significance of this route goes beyond the telecommunications sector. In wartime conditions, the resilience of communication channels, data traffic, cloud services, financial operations, logistics platforms and public digital services has become an element of national security. Therefore, the diversification of physical connectivity routes is of strategic importance.

The new corridor through Romania and Moldova may provide additional opportunities for traffic routing and redundancy towards Ukraine, particularly via the Moldovan direction, while also improving access for Ukrainian operators, internet providers and business clients to Balkan and European connectivity hubs.

RETN notes that the new route enables alternative routing towards Ukraine through Moldova and towards the Balkans through Bulgaria. This is especially important for clients seeking greater physical route diversity in Eastern and South-Eastern Europe.

Bucharest and Iași play a particularly important role in this configuration. According to the company, both cities are developing rapidly as centres of business, education and technology, while demand for reliable, high-performance infrastructure in Romania continues to grow.

According to RETN, the company operates as an independent provider of network services for IP Transit and high-capacity data transmission, connecting Europe and Asia through its own DWDM and IP/MPLS platform.

IDR comment

The Institute of Danube Research considers the launch of RETN’s new backbone route through Romania and Moldova not merely as an expansion of telecommunications infrastructure, but as part of a broader transformation of the infrastructure architecture of Eastern and South-Eastern Europe.

For Ukraine, this route is particularly important because digital infrastructure is increasingly integrated with transport, energy, customs and security systems. While road, rail, port and energy corridors through Romania and Moldova create the physical basis of regional connectivity, backbone telecommunications routes form its digital dimension.

The Romanian-Moldovan direction is especially relevant for southern Ukraine, Ukrainian Pridunavia and the wider Black Sea-Danube logistics space. In the longer term, such solutions may strengthen the resilience of digital services for businesses, telecom operators, logistics companies, the banking sector, public information systems and cross-border cooperation platforms.

“For Ukraine, the redundancy of digital routes is just as important as the diversification of transport or energy corridors. RETN’s new route through Romania and Moldova demonstrates that the region is gradually emerging as an integrated connectivity space — transport, energy, digital and security-related. For Ukrainian Pridunavia, this has practical significance, as this is where the interests of Ukraine, Moldova, Romania and the EU converge in logistics, communications and critical infrastructure resilience,” the Institute of Danube Research notes.

In this context, RETN’s digital corridor may become another argument in favour of strengthening Ukrainian-Romanian-Moldovan cooperation in the field of critical infrastructure. This is not only about data transmission speed, but also about the region’s ability to ensure the continuity of economic, administrative and security processes under crisis conditions.

For Ukraine, it is important that such routes do not remain merely external transit solutions, but become integrated into national policy on digital resilience, data centre development, cybersecurity, cross-border electronic interaction and infrastructure recovery.

In this logic, digital connectivity can become a full-fledged component of the European integration of Ukrainian regions, particularly Odesa Oblast and the Danube region.
