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.
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 Alcalá de Henares, from our open market model (published method, version 2026.07-v1):
| Item | Estimate |
|---|---|
| 5 kW rack, per month | €754 – €1,018 |
| Cost per kW per month | €131 – €177 |
| Over 3 years (36 months) | €27,144 – €36,648 |
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.

A city has no electricity of its own: the sites in Alcalá de Henares are connected to the national grid, itself interconnected with its neighbours. What is measured, and what decides, is therefore the country's generation mix. No single source dominates it: the largest, solar, supplies only 21.8% (2025). The detail: solar 21.8%, natural gas 21.6%, wind 20.4%, nuclear 18.8%, hydro 11.4%, oil (fuel oil, diesel) 3.5%. Fossil fuels (coal, gas, oil) account for 25.4% of it. A kilowatt-hour there weighs 154 g of CO2, i.e. 3 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 5.5 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 Alcalá de Henares 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.

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 Alcalá de Henares is 15 km away, in San Fernando de Henares. Short distances matter: they drive the cost of a link between two buildings, and whether a backup site is workable.
