National Layout

We operate two types of data centers: self-built and partnered. We defined “self-built” data centers as those with our owned cabinets and data center equipment housed in buildings leased from third parties. We define “partnered” data centers as the data center space and cabinets we leased from China Telecom or China Unicom through agreements. As of March 31, 2015, we operate more than 22,000 cabinets in over 80 data centers throughout more than 30 cities in China.
