Why Phocea DC

Hosting companies’ critical data close to home, in a sovereign, energy-efficient infrastructure fully integrated into the city

Phocea DC was born from a conviction: Marseille, France’s second city and the world’s sixth largest interconnection hub, deserves a digital infrastructure funded in Europe and operated in France. We rehabilitate existing buildings in the heart of the city to host, interconnect and grow the digital infrastructure of tomorrow.

Finally, a 100% French data center in Marseille. I have no regrets about migrating my servers to this data center, with its latest technologies, tightly controlled access security and, above all, such a low PUE. The Phocea team really listens to us and was there to make sure the migration and installation of my equipment went as smoothly as possible.
