1 network is listed at the sites in Yongin-si 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 Yongin-si 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, coal, supplies only 31.1% (2025). The detail: coal 31.1%, nuclear 29.6%, natural gas 27.9%, solar 6.1%, bioenergy 3.2%, oil (fuel oil, diesel) 1%. Fossil fuels (coal, gas, oil) account for 60% of it. A kilowatt-hour there weighs 417 g of CO2, i.e. 1.1 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 14.8 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 Yongin-si, and 1 within 200 km. The strongest: magnitude 5.1 in 1982, 163 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, Yongin-si 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 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 Yongin-si is 3 km away, in Yongin (3 sites). Short distances matter: they drive the cost of a link between two buildings, and whether a backup site is workable.
