Our Datacenters
A network of six datacenters across the country
From Civrieux (01 – Auvergne / Rhône-Alpes region) to Montpellier (34 – Occitanie), NEXEREN operates a network of interconnected, certified and redundant data centres.
Six complementary sites to meet your hosting needs as close as possible to your operations, with a service level tailored to each requirement.

Our network
Our data centres are spread across two major regions: Auvergne-Rhône-Alpes and Occitanie. This multi-site architecture enables you to build redundant infrastructures, replicate your environments across multiple sites, and choose the data centre best suited to your geographical, regulatory and technical requirements.
Thanks to our local presence, distance is no longer a barrier: you can choose your site based on your actual criteria – such as certifications, availability and connectivity – rather than on its proximity to your offices.

Sustainability is at the heart of our operations
At NEXEREN, performance goes hand in hand with responsibility: we operate our data centres by combining high availability with energy efficiency.
Beyond our energy contracts guaranteeing 100% renewable energy, our commitment is measured by the PUE (Power Usage Effectiveness), the benchmark indicator of a data centre’s energy efficiency, which compares total energy consumption with the energy actually used by the servers.
Whilst the industry average is around 1.5, all our sites have a PUE of less than 1.3: over 75 per cent of the energy directly powers computing operations. This efficiency is based on a simple principle: pooling resources rather than spreading them out.
Concentrating servers in a data centre designed for performance is far more efficient than having multiple corporate server rooms, which are often oversized and poorly cooled.
