| Your real-time applications running over [Cloudflare Tunnel](/cloudflare-one/connections/connect-networks/) are now faster and more reliable. We've completely re-architected the way `cloudflared` proxies UDP traffic in order to isolate it from other traffic, ensuring latency-sensitive applications like private DNS are no longer slowed down by heavy TCP traffic (like file transfers) on the same Tunnel. |

| This is a foundational improvement to Cloudflare Tunnel, delivered automatically to all customers. There are no settings to configure — your UDP traffic is already flowing faster and more reliably. |

Summary
We have launched a significant performance and reliability upgrade for all UDP traffic proxied through Cloudflare Tunnel. This change redesigns our UDP proxying system to make it faster and more resilient, particularly for high-volume applications like private DNS. With this update, latency-sensitive UDP traffic (e.g., DNS) will no longer be slowed down or blocked by heavy TCP traffic (e.g., file transfers) running over the same tunnel.
