Overview
CDNSun, founded in 2012, is a content delivery network provider based in Prague, Czech Republic. It offers services like website acceleration, video streaming, and software delivery through a network of over 50 points of presence (PoPs) worldwide. Its customer base includes businesses seeking cost-effective CDN solutions, particularly small to medium-sized enterprises. CDNSun emphasizes affordability with a pay-as-you-go model and a 15-day free trial. The service supports HTTP/2 and provides free shared SSL on its *.r.worldssl.net domain.
ChinaNetCenter, founded in 2000 as Wangsu Science & Technology Co., Ltd., is a major CDN and IDC provider headquartered in Shanghai, China. It offers content delivery, cloud computing, and security solutions, serving over 2,000 clients across industries like e-commerce, gaming, and media. The company operates in more than 70 countries, with a strong focus on the Asia-Pacific region and China, where it holds necessary licenses for operation. Its customers include notable firms like Huawei, ZTE, and Baidu. ChinaNetCenter has expanded globally, including deployments in Equinix data centers in the U.S. and partnerships in the Middle East.
Network & Architecture
CDNSun operates more than 50 PoPs across five continents, including locations in North America (e.g., Atlanta, Chicago, Dallas), Europe (e.g., Amsterdam, Frankfurt, London), Asia (e.g., Hong Kong, Singapore, Tokyo), South America (e.g., Sao Paulo), and Australia (e.g., Sydney). All edge servers use SSD drives for faster data access and have redundant connectivity to robust internet networks. The network supports global content delivery with a focus on reducing latency for websites and streaming services. Specific routing or peering details are not publicly disclosed, but the provider claims strong performance for global audiences.
ChinaNetCenter operates nearly 60 CDN acceleration nodes across Asia, Europe, America, and the Middle East, with a recent expansion into Etisalat’s network in the UAE. Its infrastructure supports high-bandwidth events like the Olympics and the English Premier League. The company leverages carrier-neutral data centers, such as Equinix’s LA1, for flexible routing and peering. Its primary strength lies in China and APAC, where it navigates regulatory requirements effectively. Global coverage is less extensive than competitors like Cloudflare or Akamai, with limited public details on Points of Presence (POPs) outside key regions.
