Customer Testimonials

  • QQ is one of China’s top four integrated portal websites, and one of the Internet companies serving the largest number of users in China.

    “We have a large customer base that encompasses most of China’s Internet users. Currently, the number of concurrent online accounts has exceeded 100 million. However, network conditions are different in different places of China leading to an interconnection bottleneck. In order to support our business development and improve user experience, we have been very cautious in selecting datacenters. We would assess the quality of a datacenter from many different aspects including network quality, cost, service, and historical operation performance. Our decision to choose 21Vianet as our service provider was made after comprehensive comparison, based on the added value that the company could provide for us. “
