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.
Internap Holding LLC, formerly Internap Corporation (INAP), was a provider of data center, cloud, and content delivery network (CDN) services, founded in 1996 and headquartered in Norcross, Georgia. Its CDN, once a key offering, leveraged the VitalStream platform and Managed Internet Route Optimizer (MIRO) for optimized content delivery. The company served enterprises, including IPTV providers like NetMax Media, with a focus on performance through its Private Network Access Points (P-NAP). In 2023, Internap rebranded to HorizonIQ, shifting focus to bare metal cloud and colocation services. Its CDN operations have been discontinued, and the company now operates as a cloud-focused business.

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.

  • Businesses needing high-throughput CDN for video streaming, gaming, or large file downloads, particularly with global audiences.
  • Companies migrating from StackPath or Lumen Technologies, leveraging CacheFly’s dedicated transition support.
  • Developers seeking an API-first CDN with flexible pricing and a free tier for testing or small-scale projects.

When it doesn’t

  • Organizations requiring advanced edge compute or serverless functions, which CacheFly does not currently offer.
  • Users needing robust WAF, bot mitigation, or rate-limiting features, as these are not publicly documented.
  • Companies focused on China-specific delivery, where CacheFly lacks a specialized license compared to providers like Tencent CDN.

History & Notes

Internap’s CDN, built on VitalStream and MIRO, was a notable player in the 2000s, with expansions in London, Tokyo, and Hong Kong. Financial challenges, including a $99.7M goodwill writedown in 2008 and multiple bankruptcies, led to asset sales and a pivot away from CDN services. The 2022 ransomware attack on ServerIntellect further disrupted its hosting operations, prompting the final shift to HorizonIQ. No official EOL notice for the CDN is publicly available, but the rebranding and asset sales indicate a complete exit from the CDN market.
