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.

IORiver is a MultiCDN platform that enables businesses to manage multiple CDN局
System: Content Delivery Networks (CDNs) simultaneously, ensuring high availability and performance without the complexity of managing each CDN separately. Founded in 2024 by former Akamai engineers Edward Tsinovoi and Michael Hakimi, IORiver is based in Tel Aviv, Israel, and serves industries like SaaS, online retail, streaming media, and finance. The platform handles over 100 petabytes of traffic monthly, offering a unified interface for configuring edge services like WAF, rate limiting, and edge computing across multiple providers. It integrates with major CDNs such as Cloudflare, Akamai, Fastly, Edgio, and Amazon CloudFront. IORiver focuses on simplifying MultiCDN adoption for businesses needing global content delivery with minimal operational overhead.
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.
IORiver does not operate its own CDN infrastructure but orchestrates traffic across multiple third-party CDNs, including
Akamai,
Cloudflare,
Fastly,
Edgio,
Amazon CloudFront,
G-Core, and
Microsoft Azure. Its Virtual Edge solution routes traffic to optimal CDN providers based on geolocation, traffic type, or cost, achieving 99.999% availability. The platform supports global content delivery with no specific POP count disclosed, relying on the combined footprints of integrated CDNs. It uses a Multi-DNS approach for resilient routing, avoiding single points of failure. Regional strengths depend on the chosen CDN providers, with flexibility to include local CDNs for markets like India or China.
