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
BytePlus operates over 1,300 PoPs across more than 70 global locations, with a focus on APAC and China, where it holds a China-licensed CDN status. Its network supports over 120 Tbps of bandwidth, optimized for video streaming and large file downloads. The architecture uses SSD-based cache servers and DNS-based load balancing for reliability. Strong peering in APAC ensures low latency, though coverage in Africa and LATAM is less extensive compared to providers like Cloudflare or Akamai.
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.

Integrations & DevEx
BytePlus supports API-driven configuration for automation, with real-time logs and log push for monitoring. It offers SDKs for integration but lacks Terraform support. Migration guides are available, covering DNS updates, SSL/TLS setup, and A/B testing for transitions. The console provides tools for managing domains, certificates, and edge functions, though developer-centric features are less extensive than Fastly or Cloudflare.
CDNSun offers an API-first approach for managing CDN services, including access to real-time logs. It provides integration support via a dashboard and API, with 24/7 technical support through email, phone, and live chat. No specific Terraform or CI/CD integrations are documented. The service includes tools for testing performance gains, such as ping tests and downloadable test files (1 MB and 20 MB).
