Overview
CacheFly, founded in 2002 and based in Chicago, IL, is a content delivery network (CDN) provider specializing in high-performance delivery of static and dynamic content. It serves businesses in video streaming, gaming, software distribution, and e-commerce, emphasizing speed and reliability. CacheFly pioneered TCP Anycast routing in 2002, which optimizes traffic delivery to the nearest point of presence (PoP). Its customers range from startups to enterprises seeking efficient content delivery. The company has gained attention for capitalizing on recent CDN industry consolidation, positioning itself as an alternative to providers like StackPath and Lumen Technologies.
Kingsoft Cloud, founded in 2012, is a leading cloud service provider in China, offering CDN, cloud storage, and computing services. It serves industries like gaming, video streaming, healthcare, and finance, with a strong focus on AI-driven solutions. The company operates as a subsidiary of Kingsoft Corporation and is listed on NASDAQ (KC) and HKEX (3896). Its customers include enterprises leveraging its infrastructure for high-performance computing and AI applications, particularly within the Xiaomi and Kingsoft ecosystems. As of 2025, it reports significant growth in AI cloud revenue and operates data centers globally.
Network & Architecture
CacheFly operates over 75 points of presence (PoPs) across all seven continents, with a strong presence in North America, Europe, Asia, South America, Australia, Africa, and the Middle East. Its network uses TCP Anycast for efficient routing, ensuring low-latency delivery. CacheFly reports a 98% cache hit ratio, with 100% availability for its S.O.S. (Storage Optimization Service) customers. The network is optimized for high-throughput use cases like large file downloads and media streaming. It has a notable footprint in Latin America compared to some competitors but may have fewer PoPs in certain regions compared to larger providers like Cloudflare or Akamai.
Kingsoft Cloud operates data centers in mainland China, Hong Kong, Russia, Southeast Asia, and North America. Specific POP (Point of Presence) counts are not publicly disclosed, but the provider emphasizes a global footprint with strong coverage in APAC, particularly China. Its infrastructure supports high-performance computing for AI and gaming, with robust peering for low-latency delivery in the region. Limitations may include less extensive coverage in EMEA and LATAM compared to providers like Akamai or Cloudflare. The service is optimized for China’s regulatory environment, holding necessary licenses for operation.
