6 networks are listed at the sites in Leuven according to public interconnection registries. That number drives your negotiating power: every carrier inside the building is one more quote, with no civil works. 1 Internet exchange point is 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 OVHcloud, Cloudflare: they are present at the exchange point where one site in the city is a point of presence. Reaching your cloud over an exchange point rather than the public Internet changes latency, and above all the price of data egress.
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 Leuven 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, nuclear, supplies only 33.1% (2025). The detail: nuclear 33.1%, natural gas 21.5%, wind 18.8%, solar 14.3%, oil (fuel oil, diesel) 6.4%, bioenergy 5.2%. Fossil fuels (coal, gas, oil) account for 27.9% of it. A kilowatt-hour there weighs 150 g of CO2, i.e. 3.1 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 5.3 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, 3 earthquakes of magnitude 5 or above have been recorded within 100 km of Leuven, and 3 within 200 km. The strongest: magnitude 5.5 in 1976, 75 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.

With a single listed site, Leuven cannot support a disaster-recovery plan spread over two separate buildings within the same town. A second site remains necessary, and it is found in the nearby cities listed below. 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 Leuven is 16 km away, in Nossegem. Short distances matter: they drive the cost of a link between two buildings, and whether a backup site is workable.
