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.
KeyCDN is a content delivery network (CDN) provider founded in 2012, headquartered in Wilen, Switzerland. It specializes in accelerating the delivery of web content, such as HTML, JavaScript, images, and videos, through a global network of edge servers. The service is designed for businesses of all sizes, from small blogs to enterprise websites, offering features like real-time analytics and DDoS protection. KeyCDN emphasizes ease of integration with a user-friendly dashboard and API, making it accessible for developers and SMBs. It supports a wide range of use cases, including e-commerce, media, and gaming, with a focus on performance and security.

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.
KeyCDN operates over 50 points of presence (POPs) across North America, Europe, Asia-Pacific, Latin America, and other regions, ensuring global coverage. Its network leverages SSD storage and HTTP/3 for efficient content delivery. The service uses a tiered caching system and supports origin shielding to reduce load on origin servers. KeyCDN has strong peering agreements with major ISPs, optimizing latency and throughput. Its regional strengths include robust performance in North America and Europe, though coverage in Africa and parts of Asia may be less extensive compared to larger providers like Cloudflare or Akamai.
