Good morning and good evening, everyone. Thank you for joining us for the earnings call today. Firstly, we are pleased to announce another solid quarter of healthy growth in our core business. 21Vianet continues to evolve with China's transforming Internet infrastructure industry as we see the continued rapid adoption of cloud solutions, increasing specialization of services as well as healthy demand for co-location services from Internet companies demanding expanded data applications as well as a variety of other industries, including financial institutions, which are seeking additional services -- which are seeking additional services like disaster recovery within our data centers.
As more new cloud-based services emerge, like artificial intelligence, Internet of Things, Blockchain and big data, we believe the growing potential for computing capacity and storage as well as Internet traffic will grow exponentially in China. To strengthen the relationship in that IDC market, we have set a plan to build an unparalleled digital real estate platform, aiming to add 80,000 to 100,000 new cabinets over the next 5 to 7 years.
Let me start by talking in a bit more detail about our recent move to form our strategic joint venture with Warburg Pincus to build a digital real estate platform in China. The data center industry as a whole is transforming quickly towards specializations. One side is a traditional retail co-location business, and the other side is a large-scale wholesale and a customized data center business like Digital Realty Trust model. These changes are the impetus behind several of our recent restructuring efforts and partnerships.
Similar to the specialization we have seen in the U.S. market, our strategy is to focus on asset-light business, which will be separated from the capital intensive business. Our partnership with Warburg Pincus not only brings in extensive network resources but also brings in their expertise in the real estate industry.
For 21Vianet, with our deep industry experience in data center operation, we see the separation of this full [ph] business as a solid strategic move, which will benefit us with a significant reduction in CapEx for future buildouts and a tremendous growth opportunities by more specifically focusing on both the wholesale data center and the retail market in China.
Next, I would like to talk about the progresses we achieved in our hosting-related business. For our core IDC business, we added over 2,300 new cabinets in our self-built data centers during the quarter. The majority of the increase comes from our newest data center in Beijing, which opened towards the end of the third quarter. Supported by solid growth in billable cabinets, our data center utilization rate continued to increase to 77.9% despite this large additions.
Our Cloud business showed continuous strength in terms of revenue and the profitability. We recently launched the IBM Bluemix services for general availability in October to all China-based users, which added services like artificial intelligence and Blockchain.
CCTV.com was one of the early adopters of IBM Bluemix services. We have great expectations in this deepening partnership with IBM and believe it will facilitate a much wider range of cloud-related cooperation opportunities between the 2 companies and building a robust and comprehensive cloud ecosystem in China.
I also want to touch upon our hybrid IT business strategy. Since we announced this strategy at the start of the year, we have welcomed more and more new partners into our ecosystems, including 2 newly added customers: one is Aetna, one of the 5 largest house insurance providers in the U.S.; and the other is Bupa, U.K.'s leading healthcare specialist. We provide a complete package of customized, secure and carrier-neutral IT solutions to them, enabling them to provide stable and safe services to their customers.
Such high-profile partners are able to rely upon 21Vianet solution to help them achieve both flexibility and superior performance for their hybrid IT needs.
I also like to talk a bit about our interconnection platform. As you are aware, this platform is similar to the Equinix cloud exchange model. We have been gradually rolling it out in our data center operations with several pilot projects. Our interconnection platform enables our data center customers to achieve stable, secure and fast data transmissions within our data center through interconnection technology, no matter where the business centers are located. It also allows for cloud exchange, which enables customers to establish more secure connections from their applications to the cloud. And the data exchange with Internet service providers.
Our interconnection platform will significantly accelerate users' connections and the reduced customer bandwidth cost.
We are so far very pleased with the progress of this pilot project and hope we can soon roll out this high-margin offering to all of our data center customers.
For CDN and the MNS business, we continued to experience ongoing challenges as a result of the combination of the market competition and the regulatory restrictions. We see some early signs of stabilization, and we're working diligently to streamline our cost structure, which will help us begin to grow with steady margins as demand solidifies.
In summary, we are pleased with the strong performance in our core IDC business and the closing of our joint venture with Warburg Pincus. This helps position us more strategically in terms of scope of service offerings, world-class partnerships, financial resources, capital structure and the industry expertise to capture this industry's solid, secular growth and aim to become the #1 player with the best-in-class data center facilities, serving both the wholesale and the retail co-location market in China going forward.
With that, I would like to turn the call over to Terry, our CFO, to go through our financial results. Terry?
