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 Cesson-Sévigné, from our open market model (published method, version 2026.07-v1):

| Cost per kW per month | €137 – €159 |
| Over 3 years (36 months) | €28,440 – €33,048 |
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.

10 networks are listed at the sites in Cesson-Sévigné according to public interconnection registries. That number drives your negotiating power: every carrier inside the building is one more quote, with no civil works.
Declared certifications: ISO 27001, ISO 50001, HDS. A certification is verified site by site and carries an expiry date: ask for the certificate, not the logo. Sites in this city are operated by companies outside US jurisdiction, hence outside the CLOUD Act.
A city has no electricity of its own: the sites in Cesson-Sévigné 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.

Since 1970, 0 earthquake of magnitude 5 or above has been recorded within 100 km of Cesson-Sévigné, and 1 within 200 km. The strongest: magnitude 5 in 2001, 166 km away. 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.

No Internet exchange point is listed here: traffic will run over transit bought from a carrier, which is billed by bandwidth. No rate is published by the operators in this city: pricing is on request, and we do not estimate it on their behalf.
The nearest site outside Cesson-Sévigné is 2 km away, in Rennes. Short distances matter: they drive the cost of a link between two buildings, and whether a backup site is workable.
