Nanjing has 2 data centers listed on DataColoc, operated notably by Princeton Digital Group, BDx DC Services Limited. Compare colocation (rack, half-rack, 1U), pricing, certifications and connectivity, then get an instant costed estimate.
Server colocation in Nanjing (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 2 data centers offering colocation in Nanjing, including Princeton Digital Group, BDx DC Services Limited. Its top-connected site lists 1 network.
a full rack is priced on electrical power (kVA), IP transit and cross-connects. Compare the 2 data centers in Nanjing to get a costed quote.
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 Nanjing, from our open market model (published method, version 2026.07-v1):
| Item | Estimate |
|---|---|
| 5 kW rack, per month | €857 – €1,286 |
| Cost per kW per month | €151 – €231 |
| Over 3 years (36 months) | €30,852 – €46,296 |
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.

1 network is listed at the sites in Nanjing according to public interconnection registries. That number drives your negotiating power: every carrier inside the building is one more quote, with no civil works.
A city has no electricity of its own: the sites in Nanjing 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 54.3% of its electricity from coal (2025). The detail: coal 54.3%, hydro 13.2%, solar 11.1%, wind 10.7%, nuclear 4.6%, natural gas 3.2%. Fossil fuels (coal, gas, oil) account for 58.3% of it. A kilowatt-hour there weighs 525 g of CO2, i.e. 1.1 times 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 18.6 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, 2 earthquakes of magnitude 5 or above have been recorded within 100 km of Nanjing, and 2 within 200 km. The strongest: magnitude 5.5 in 1974, 42 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 Nanjing is 263 km away, in Shanghai (11 sites). Short distances matter: they drive the cost of a link between two buildings, and whether a backup site is workable.
