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.
OnApp CDN is a federated content delivery network designed for hosting providers, utilizing spare capacity in OnApp Clouds to deliver content globally. It supports HTTP push, pull, and streaming/live streaming, catering to hosting providers and enterprises managing web content delivery. The platform integrates with OnApp Cloud, enabling users to leverage a network of edge servers for improved performance. It is primarily used by service providers and enterprises needing scalable CDN solutions. The service is operational as of August 16, 2025, with recent updates enhancing its reporting capabilities.

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.
OnApp CDN operates a global network of Points of Presence (PoPs) by leveraging spare capacity from OnApp Clouds, though specific PoP counts are not publicly detailed. It uses a federated model, combining edge servers from multiple cloud hosts to ensure broad geographic coverage. The platform supports content delivery across regions including North America, EMEA, APAC, and others, with synchronization between CDN and OnApp Cloud occurring every 20 minutes by default. Regional strengths include flexibility for hosting providers, but limitations may arise from reliance on third-party cloud capacity, potentially affecting consistency in less dense regions.
