But it works on the web, not on the game port. Here is where it helps and where it does not.

It works on the web, not on the game port, so it does not improve your Minecraft server's ping. Use a CDN for your community website and store, and protect the game with dedicated mitigation. ## What a CDN is[](https://streethosting.com.br/en/guides/infrastructure/what-is-a-cdn-game-server#o-que-e-cdn) CDN stands for content delivery network. Instead of every visitor fetching files from your server, the CDN keeps copies spread around and serves them from the point closest to each person. The result is faster loading and less load on the origin. It is a web tool, closely related to [web layer protection](https://streethosting.com.br/en/guides/infrastructure/cloudflare-game-server-protection). ## Where a CDN helps[](https://streethosting.com.br/en/guides/infrastructure/what-is-a-cdn-game-server#onde-ajuda) * Your community website loads faster for everyone. * Modpack downloads and other heavy files get snappy. * The panel and the store hold up under traffic spikes. ## Where it does not help[](https://streethosting.com.br/en/guides/infrastructure/what-is-a-cdn-game-server#onde-nao-adianta) A CDN does not speed up your game ping and does not protect the server port. That traffic takes another path. Expecting a CDN to fix game latency leads to frustration. For ping, what counts is the distance to the data center and the network, as explained in [what latency and ping are](https://streethosting.com.br/en/guides/infrastructure/what-is-latency-and-ping). ## CDN and protection[](https://streethosting.com.br/en/guides/infrastructure/what-is-a-cdn-game-server#cdn-e-protecao) For a website, a CDN with protection absorbs part of the attacks at the web layer. For the game, though, the defense has to understand the server's protocols. Learn about this difference in [Anti-DDoS for game servers](https://streethosting.com.br/en/guides/infrastructure/anti-ddos-game-server-brazil). ## When to use one[](https://streethosting.com.br/en/guides/infrastructure/what-is-a-cdn-game-server#quando-usar) * Community website and panel on the CDN * Modpack downloads sped up * Game protection handled separately * Nearby data center for game ping A CDN and game protection solve different problems, and they complement each other.

It keeps copies of your content at many points around the world and delivers it from the one closest to the visitor. That speeds up loading of websites, images and downloads and reduces the load on the origin server. Does a CDN speed up my Minecraft server's ping? Not directly. A CDN works with web traffic. The game port takes a different path. For game latency, what matters is how close the data center is and the quality of the network, not a CDN. Does a CDN protect against DDoS? For the website and the panel, a CDN with protection helps absorb attacks at the web layer. But it does not protect the game port, which needs specific mitigation for the server's protocols. So when is a CDN worth using on a game project? It is worth it for the community website, the panel, the store and modpack downloads. Those web resources gain speed and resilience. The game server itself depends on another layer of protection. Next step See Minecraft Pro Managed hosting on Ryzen with modpacks, optimized Paper and technical support.
