euNetworks launched a new 1,057 km (657-mile) long-haul fibre route connecting Paris and Milan through the Alps, creating a shorter and geographically diverse alternative to routes that commonly run south through Lyon and Marseille. The new corridor links two major European data center markets as demand for AI infrastructure, cloud services, and high-capacity interconnection drives additional investment in continental fibre networks.
The route connects directly with euNetworks’ owned and operated metropolitan networks in Paris and Milan. The Paris network reaches 38 on-net data centers, while the Milan network reaches 18 on-net facilities. Customers can also access euNetworks’ broader European footprint of more than 600 connected data centers across 18 metropolitan networks and an intercity backbone spanning 53 cities in 17 countries.
The Paris-Milan deployment follows the completion of euNetworks’ Frankfurt-Milan route via Zurich in October 2025. Together, the projects expand the company’s direct north-south connectivity infrastructure across key European data center markets and provide additional routing options between Frankfurt, Zurich, Milan, and Paris.
• Route length: 1,057 km (657 miles) between Paris and Milan
• Network path: New geographically diverse route through the Alps
• Alternative corridor: Shorter option compared with routes running via Lyon and Marseille
• Paris metro network: 38 on-net data centers
• Milan metro network: 18 on-net data centers
• European footprint: More than 600 connected data centers
• Network reach: 18 metropolitan networks and an intercity backbone spanning 53 cities in 17 countries
• Previous expansion: Frankfurt-Milan route via Zurich completed in October 2025
“The new route between Paris and Milan is a prime example of our dedication to providing customers with the most direct, diverse connectivity options in Europe. As demand for AI, cloud and data driven connectivity rises, shorter routes and diversity become increasingly crucial,” said Marisa Trisolino, CEO of euNetworks.
🌐 Analysis: The Paris-Milan route adds physical path diversity to one of Europe’s increasingly important north-south data center corridors as AI infrastructure deployments increase demand for fibre capacity between major compute and interconnection markets. The combination of the Paris-Milan and Frankfurt-Zurich-Milan routes strengthens euNetworks’ position in long-haul infrastructure connecting European data center hubs, alongside network operators expanding fibre capacity and route diversity to support hyperscale cloud and AI workloads.
