The CDN rides on Tata’s global infrastructure which is the largest Tier 1 network in the world. Tata’s ownership of the network and peering relationships enable it to be very competitive when it comes to price. | Founded in 1998, publicly traded on NASDAQ (CCIH), ChinaCache is the first CDN in China and generally considered to be one of the better CDNs for China delivery because of their network, knowledge and experience from working with (enterprise) multinational customers. The ChinaCache network and services are not limited to mainland China and ChinaCache has been growing steadily outside China in the past years. |
