ByteDance Taihang Computing Center (Volcano Cloud)

The Taihang Computing Center sits in Guangling County under Datong, Shanxi province, part of China's 'East Data, West Computing' push to move compute capacity toward power- and land-rich western regions. It is developed by Volcano Cloud (Datong) Technology Co., Ltd, a company local government and corporate filings trace as wholly owned by Beijing Zitiao Network Technology Co., Ltd, itself a subsidiary of Douyin Group (Hong Kong) Ltd — placing the project directly in ByteDance's own ownership chain rather than under an anchor-tenant lease with an operator such as Chindata or GDS, the model ByteDance typically uses elsewhere. Construction proceeds in phases: Phase 1 broke ground in 2023 on a roughly 220-mu site with four data center buildings and a dedicated 110kV substation; Phase 2, approved by local authorities in January 2025, covers about 205,000 sqm of land and over 207,000 sqm of floor area across six data center buildings, a six-story integrated building, generator buildings and a 220kV substation, with reported cabinet capacity implying on the order of 190MW of IT power; Phase 3 land procedures were underway in early 2025. Total investment across all phases is reported at roughly RMB 12 billion. No independent Uptime Institute or TIA-942 certification has been published for the site, and exact aggregate MW and cooling design have not been disclosed by ByteDance itself.
