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 Microsoft Azure, Tencent Cloud: 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.
A city has no electricity of its own: the sites in Yongsan-gu 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 Yongsan-gu, and 1 within 200 km. The strongest: magnitude 5.1 in 1982, 139 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, Yongsan-gu 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 Yongsan-gu is 2 km away, in Seoul (19 sites). Short distances matter: they drive the cost of a link between two buildings, and whether a backup site is workable.
