Overview
BelugaCDN is a content delivery network (CDN) provider founded in 2014, designed to accelerate website content delivery globally at a low cost. It operates a dual-stack IPv4 and IPv6 network, focusing on delivering static content like images and videos to users across various devices. The service is utilized by small to medium-sized businesses, e-commerce platforms, and media sites seeking affordable CDN solutions. BelugaCDN emphasizes straightforward caching, real-time analytics, and easy integration with existing web infrastructure. The company is headquartered in Miami, Florida, and operates as a subsidiary of Xcitium following its acquisition in 2018.
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. CDNSun emphasizes affordability with a pay-as-you-go model and a 15-day free trial. The service supports HTTP/2 and provides free shared SSL on its *.r.worldssl.net domain.
Network & Architecture
BelugaCDN maintains 28 points of presence (POPs) across five continents, with 9 high-capacity “SuperPOPs” in key locations such as New York, Miami, Dallas, San Jose, Seattle, Chicago, London, Amsterdam, and Frankfurt. Its network is optimized for North America and Europe, with smaller-capacity POPs in Asia, Latin America, and Oceania, including São Paulo, Bangalore, Singapore, and Sydney. The provider uses proxy-based authorization and a private high-speed global network to ensure low-latency content delivery. Plans to upgrade Bangalore and Singapore POPs to SuperPOPs were noted in 2017, but no recent updates confirm completion. Limitations include limited presence in China and the Middle East, which may impact performance for users in those regions.
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.
