Load Balancing - UDP and ICMP Monitor Support for Private Load Balancing Endpoints

Cloudflare Load Balancing now supports UDP (Layer 4) and ICMP (Layer 3) health monitors for private endpoints . This makes it simple to track the health and availability of internal services that don’t respond to HTTP, TCP, or other protocol probes. What you can do: Set up ICMP ping monitors to check if your private endpoints are reachable. Use UDP monitors for lightweight health checks on non-TCP workloads, such as DNS, VoIP, or custom UDP-based services. Gain better visibility and uptime guarantees for services running behind Private Network Load Balancing , without requiring public IP addresses. This enhancement is ideal for internal applications that rely on low-level protocols, especially when used in conjunction with Cloudflare Tunnel , WARP , and Magic WAN to create a secure and observable private network.
