Paris has 46 data centers listed on DataColoc, operated notably by Telehouse - Global Data Centers, Equinix, Inc., Digital Realty, UltraEdge, Global Switch, Treefaz. Compare colocation (rack, half-rack, 1U), pricing, certifications and connectivity, then get an instant costed estimate.
Server colocation in Paris (server housing) means installing your own servers in a rack or cabinet (42U) inside a secure data center: redundant power, cooling, 24/7 security and multi-carrier connectivity. DataColoc lists 46 data centers offering colocation in Paris, including Telehouse - Global Data Centers, Equinix, Inc., Digital Realty, UltraEdge. Its top-connected site lists 360 networks and 16 internet exchange points (IXPs).
In Paris, observed rates start from 49 €/mo for a 1U server. A full rack (42U) is priced on subscribed power (kVA), IP transit, cross-connects and contract term. Run the comparator for an exact quote for your needs.

None: “housing” and “colocation” mean the same thing — hosting your own servers in a third-party data center, as opposed to renting a dedicated server or public cloud.
13 of the 46 data centers listed in Paris declare ISO 27001. Filter by certification (ISO 27001, HDS, PCI-DSS) in the comparator to keep only compliant sites.
Learn the basics: colocation, 42U rack, cross-connect, IP transit, Tier III/IV.
Costed answers: how much does a rack cost?, cross-connect pricing, colocation or cloud? — and the colocation price barometer.
Beyond listed prices, here is the computed cost of a standard 5 kW rack in Paris, from our open market model (published method, version 2026.07-v1):
| Item | Estimate |
|---|---|
| 5 kW rack, per month | €768 – €1,034 |
| Cost per kW per month | €133 – €180 |
| Over 3 years (36 months) | €27,648 – €37,224 |
What this covers: local industrial energy tariff, site efficiency (PUE), retail colocation margin and local market tightness. What it does not: IP transit, cross-connects, setup fees and PDUs — priced site by site in the comparator.
An estimate, not an offer. It is a model, with an open method and a version — not a contractual rate. A quote prices your actual configuration. Think the model is wrong? The method is published: tell us where.
Compare data centers in Paris →Paris has 46 data centers, operated by Telehouse - Global Data Centers, Equinix, Inc., Digital Realty, UltraEdge. Declared design level: Tier III. That level describes the building's redundancy, not a contractual availability commitment: only the contract carries one. Available formats range from 1/4 baie to 1U (1/4 baie, 1/2 baie, 1 baie, 1U): you can start small here, without renting a whole rack. The smallest recorded commitment starts at €49/month for one U, excluding power and connectivity.
360 networks are listed at the sites in Paris according to public interconnection registries. That number drives your negotiating power: every carrier inside the building is one more quote, with no civil works. 15 Internet exchange points are reachable from these sites, which cuts latency to the large content networks and the cost of transit. The large networks reachable directly from these sites, without buying transit, are Alibaba Cloud, Amazon Web Services, DigitalOcean, Google, Hetzner, IBM Cloud, Microsoft Azure, Oracle Cloud and 9 more: they are present at the exchange points where 11 of the 46 sites in the city are points of presence. Reaching your cloud over an exchange point rather than the public Internet changes latency, and above all the price of data egress.
Declared certifications: ISO 27001, PCI DSS, ISO 50001, HDS, ISO 22301, SOC 2, ISO 27701. A certification is verified site by site and carries an expiry date: ask for the certificate, not the logo. Note: part of the operation falls under a US-jurisdiction company, hence under the CLOUD Act. Hosting in Europe is not enough to escape it: what counts is the provider's nationality, not the building's address.
A city has no electricity of its own: the sites in Paris are connected to the national grid, itself interconnected with its neighbours. What is measured, and what decides, is therefore the country's generation mix. That grid draws 68.8% of its electricity from nuclear (2025). The detail: nuclear 68.8%, hydro 10.4%, wind 8.2%, solar 5.6%, natural gas 3%, oil (fuel oil, diesel) 1.8%. Fossil fuels (coal, gas, oil) account for 5.1% of it. A kilowatt-hour there weighs 41 g of CO2, i.e. 11.2 times less than the world average (458 g), 2025 figure. Concretely: a 3 kVA rack, in a site with a PUE of 1.5, draws 35,478 kWh a year and therefore emits 1.5 tonnes of CO2 a year here. The same rack, same hardware, same PUE, would emit 16 tonnes on a world-average grid. The building has nothing to do with it: the country does.

No earthquake of magnitude 5 or above has been recorded within 200 km of Paris since 1970, according to the US Geological Survey's global catalog. This record covers 56 years, which is short on a seismic timescale: no recorded earthquake does not mean no hazard. It does not replace the statutory zoning, which alone binds construction.

The nearest site outside Paris is 5 km away, in Aubervilliers (2 sites). Short distances matter: they drive the cost of a link between two buildings, and whether a backup site is workable.
