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.
Fastly operates over 60 points of presence (POPs) globally, with a focus on major population centers for low-latency content delivery. Its global anycast network optimizes routing, but its smaller POP count compared to competitors like Akamai or Cloudflare may limit coverage in some regions. Fastly has strong peering agreements, enhancing performance for high-traffic sites. It excels in North America, EMEA, and APAC but has less presence in Africa and LatAm. The platform leverages WebAssembly for edge computing isolation and resiliency.
