V2ray Slow Dns Server Review

Slow DNS servers do not just increase latency; they can trigger destructive timeout spirals. Many V2Ray clients have hardcoded or default timeouts for connection establishment. If a DNS lookup takes longer than expected, the client may abandon the request and retry. This retry logic floods the proxy server with duplicate queries, increasing load and further slowing DNS resolution for all users on that server. In worst-case scenarios, the client interprets the slowdown as a connectivity failure and begins restarting the entire V2Ray service, leading to intermittent disconnections and an unreliable user experience.
