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.

Network & Architecture
BlazingCDN operates over 25 points of presence (PoPs) globally, with 50 GBps uplink per server and a total network capacity exceeding 10 Tbps. It uses Anycast routing to optimize content delivery by directing traffic to the nearest server. The network has strong coverage in North America, Europe, Asia-Pacific, and Latin America, but lacks PoPs in Africa and the Middle East. Its architecture supports a private global backbone with 4.5 petabytes of cached files and an average latency of 27 ms in the USA and EU.
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.
