Network & Architecture

The network is particularly strong in Europe and North America, with recent expansions in Asia through partnerships like Exa Infrastructure for 400G and 100G wavelengths. While it has comprehensive global coverage, its presence in Africa and certain parts of APAC may be less dense compared to competitors like Cloudflare or Akamai.

Specific POP (Point of Presence) counts are not publicly disclosed, but the provider emphasizes a global footprint with strong coverage in APAC, particularly China. Its infrastructure supports high-performance computing for AI and gaming, with robust peering for low-latency delivery in the region. Limitations may include less extensive coverage in EMEA and LATAM compared to providers like Akamai or Cloudflare. The service is optimized for China’s regulatory environment, holding necessary licenses for operation.
