Distributed Deployment

Our data centers are located in more than 30 cities in China as of the data of this report. Our nationwide network of data centers not only enables us to serve customers in extended geographic areas, but also establishes a national data transmission network that sets up connections among carriers and service providers in various locations.

We build and operate our data centers in compliance with high industry standards in order to provide our customers with secure and reliable environments that are necessary for optimal internet inter-connectivity. Our data centers generally feature:

Resilient Power —Redundant, high-capacity and stable power supplies, backed by uninterruptible power supply, or UPS, and diesel generators;

Physical Security —Round-the-clock monitoring by on-site personnel, which includes verification of all persons entering the building, security barriers, video camera surveillance and security breach alarms;

Controlled Access —Access to the buildings, data floors and individual areas designated for particular customers via individually-programmed access cards and visual identification;

Fire Detection and Suppression —Sensitive smoke detectors linked to building management systems provide early detection to help avoid fire, loss and business disruption. These are complemented by an environmentally-friendly gas-based or water mist fire suppression system to put out fires;

Air Conditioning —To ensure optimal performance and avoid equipment failure, all data center floors are managed to make sure that customers’ equipment is maintained at a controlled temperature and humidity;

24/7 Support —We staff our data centers with capable and experienced service teams and we believe we were the first data center service provider in China to offer 24/7 customer service.
