The following are our key business milestones: In 2001, we started our business as an IT service provider. Our initial focus was on business continuity and disaster recovery solutions. Many of our early customers were financial service institutions with demanding IT compliance standards. To guarantee the reliability and availability of services to them, we leased data center capacity from third parties. In 2009, after realizing that there was a shortage of qualified data center capacity in key markets, we began developing our own data centers, thereby entering the data center business. We established our presence in Shanghai and Chengdu in 2010 and 2011, by bringing three data centers into service in these markets.
