AT&T announced a $200M data center on a 130-acre site within T5's Kings Mountain data center park in 2014; contemporary reporting (WCNC, DCD, Data Center Knowledge) cited a 14-year expansion plan targeting ~900,000 sq ft of data floor space total — a long-run target, not the current built footprint, so sqft is left null here rather than overclaiming. Address (209 Countryside Rd, Kings Mountain, NC 28086) is from Baxtel's facility listing; coordinates are a building-level OSM/Nominatim geocode of that address, distinct from the Disney and T5/Ensono buildings elsewhere on Countryside Rd / Riverside Ct in the same corridor.
