At the load balancer layer, only CDN IP ranges should be accepted, ideally requiring mutual TLS between the edge and the origin (which Cloudflare calls Authenticated Origin Pulls), and per-client rate limits, connection limits, client body/header timeouts and maximum body size should be set. The key lines return a cheap 404 for sensitive patterns, such as `location ~ /\.(?!well-known) { return 404; }` and `location ~* \.(env|ya?ml|sql|bak|old|log)$ { return 404; }`.

UnverifiedA CDN distributes static and cacheable content to nodes around the world, so user requests are answered nearby and the origin therefore does not see most of the traffic; a WAF performs rule matching on requests at the nodes, and can allow, challenge, rate-limit or block based on conditions such as path, method, request headers, User-Agent and IP reputation.68% similarUnverifiedMajor cloud providers and CDNs have deployed a large number of nodes worldwide, but critical data centers and network exchange points remain concentrated in a limited number of geographic locations, and geopolitical conflict, natural disasters or physical attacks can change traffic paths instantly and affect service availability68% similarUnverified由于Cloudflare的Anycast特性，所有边缘节点都能处理任何域名的请求，将DNS指向任意一个Cloudflare IP都能正常工作，区别仅在于连接质量66% similarUnverifiedIn response to abnormally high-frequency requests, site operators can apply rate limiting or blocking for specific IP ranges at the firewall or reverse proxy layer (such as Nginx or Cloudflare).65% similarUnverifiedCDNs reduce physical network transmission latency by deploying edge nodes globally to cache static assets on servers closest to users.64% similar
