EXA removes major European network bottleneck by upgrading Marseille to Paris route

News and Business

EXA Infrastructure has announced a major investment to enhance network diversity and capacity between Marseille and Paris to address one of Europe’s critical connectivity constraints.

For more than 15 years, the Marseille to Paris corridor has represented a key bottleneck for data traffic moving between southern Europe, North Africa, and the rest of the continent.

EXA were the first operator to provide new low loss G.652D fibre between Paris and Marseille in 2024 and is now increasing the fibre count on that route due to unprecedented demand for access to subsea cables. And at the same time, the operator is delivering enhanced route diversity between those critical hubs with a new and fully geographically diverse Paris to Dijon to Marseille route.

This announcement follows EXA’s recent €1.3 billion refinancing, which has strengthened the company’s capital structure and enabled accelerated investment in its pan-European network.

“Enhancing network diversity and removing long-standing constraints like the Marseille–Paris corridor is central to our mission of delivering a more resilient and scalable digital infrastructure for Europe,” said EXA Infrastructure SVP Network Investments and Products Steve Roberts. “This investment directly supports the needs of hyperscalers, AI and HPC providers, and enterprise customers who depend on high-performance, low-latency connectivity.”
