New international backbone to connect Poland, Czechia, Slovakia and Hungary with EXA’s hyperscale network in Germany and Austria.
London, September 4th, 2025 – EXA Infrastructure, the largest dedicated digital infrastructure platform connecting Europe and North America, today announced Project Visegrád, a landmark fibre deployment designed to transform connectivity across Central Europe.
Named after the historic political, economic and cultural alliance of Poland, Czechia, Slovakia and Hungary, Project Visegrád represents the largest pan-European backbone fibre deployment in the region in the last 25 years.
The project will deliver new high-capacity international fibre routes linking Warsaw, Poznań, Prague, Bratislava and Budapest directly into EXA Infrastructure’s hyperscale backbone in Berlin, Frankfurt and Vienna. In parallel, EXA will expand its metro fibre footprints in Warsaw, Prague, Bratislava and Berlin to connect leading carrier-neutral data centres.
“Central Europe is one of the fastest-growing digital economies in Europe, yet its international connectivity has historically lagged Western Europe,” said Jim Fagan, CEO of EXA Infrastructure. “With Project Visegrád we are building the resilient, scalable backbone needed to unlock the region’s full potential, while extending EXA’s reach into new growth markets across the Baltics, Balkans, Turkey and beyond.”
The new backbone will be built with HDPE ducts containing multiple microducts to maximise scalability and flexibility. The initial deployment will use 216-fibre Corning Ultra G.652D cable, while the microduct design enables seamless upgrades to next-generation technologies such as hollow-core fibre.
To ensure ultra-high availability, the majority of the routes are within protected corridors adjacent to oil and gas infrastructure such as the Druzhba (“friendship”) oil pipeline.
“This infrastructure will set a new benchmark for optical performance and resilience in Central Europe,” added Fagan. “It will also provide a future-proof foundation for hyperscalers, carriers and enterprises that require the highest standards of connectivity.”
The first Project Visegrád routes are expected to be ready for service in mid-2026, with additional routes scheduled through 2027.
