MRS3 is an old submarine base built by the Germans during the Second World War, never completed nor used. In 2018, Interxion became the owner of this unique site.

Interxion overcame the challenge of preserving its historic importance, and at the same time transforming it into a global Internet hub for enterprises, cloud and digital media platforms.

This atypical building is Interxion’s third data centre in our Marseille campus, situated next to MRS2, and just 4km from MRS1.

This site impresses with its size and history. It is strategically located on the Mediterranean coast, offering access to 4.5 billion people across EMEA and Asia via the 14 subsea cables that connect the city to these regions.

Digital Media

To remain competitive, online gaming, video on demand, social networks and live events companies need to find the best location to create, store and distribute their content.

Interxion’s MRS3 data centre provides them with a unique community of partners to extend their audience to 4.5 billion people across EMEA and Asia with an optimized user experience.


Energy Efficiency

Energy efficiency is at the heart of businesses’ strategy willing to improve their environmental impact. 

Interxion is committed to managing its resources responsibly now and in the future. Constantly innovating to improve the way we design and operate our data centres is a priority. 

Customers at Marseille campus benefit from having 100% of power consumption produced from renewable sources.



Enterprises embracing cloud today face security and performance challenges.

The Marseille campus brings together the largest cloud platforms such as Microsoft Azure, Amazon Web Services and Google Cloud Platform serving EMEA markets.

This Marseille expansion is a perfect example of how we can quickly deploy custom, automated infrastructure to nearly any market in the world,” said Zachary Smith, CEO at Packet. “As we work with innovative clients like Hatch to push services ever closer to the edge, Interxion continues to be a valuable partner that aligns perfectly with our needs.

At Yahoo, we are continuously improving our performance to serve more than a billion Yahoo users globally. We select strategic locations for our edge locations such as Vienna and Marseille, which gives us the ability to serve our users more reliably, faster and cheaper.


CenturyLink has built out a dense metro fibre footprint in Marseille, creating a ring that spans major business districts and connects the city's core data centres. This network expansion in MRS2 will provide CenturyLink customers with local and international high-speed connectivity services from Interxion's data centres. It will also facilitate direct and secure connectivity to enterprises by means of the metropolitan ring that spans major business districts.


Colocation also allowed Shadow the flexibility to grow its infrastructure to close the gap between even more users. The company expanded to Interxion’s Marseille campus, one of the world’s most dynamic content hubs, connected through more than 14 submarine cable systems. As part of our expansion strategy, we want to be closer to our French users, especially in the south. But it also [offered] us the capacity to reach Spain, Italy and maybe Greece,” said Jérôme Arnaud,
