LG Uplus (LG U+) is South Korea’s third-largest mobile carrier, but it is also one of the country’s biggest commercial data center operators, running a network of internet data centers (IDCs) it began building in 1999 with Seoul’s Nonhyeon Center. As of 2025-2026 the company operates roughly 14-16 data centers across South Korea, including several hyperscale-class facilities in the Seoul/Gyeonggi metro area, and is building a massive new AI-focused data center in Paju, Gyeonggi Province, slated for completion around 2027 with roughly 200MW of confirmed power capacity. LG U+ sells colocation (racks, cages, and suites) to enterprise customers alongside internet access and CDN services, and has recently pushed hard into AI-optimized infrastructure — including liquid and immersion cooling development — branding its newer builds as “AI-Ready” or “AIDC” facilities aimed at GPU-based training and inference workloads.
