CDNsun is a smaller Czech Republic-based CDN that explicitly documents adult content as permitted in their published knowledgebase - one of the few providers to state this in writing. They operate 50+ PoPs across five continents on SSD infrastructure with a straightforward pay-as-you-go per-GB model, a free trial, and no minimum monthly commitment. That makes it accessible for operators testing delivery before committing to a larger plan.

Customer support is described as basic across multiple reviews. Network depth and feature set lag behind bunny.net or CDN77, but the explicit AUP clarity is valuable for operators who want written confirmation.
