Load Balancing

Load Balancing now supports pool sets

Cloudflare Load Balancing now supports pool sets through the API. Pool sets combine geographic matching with location-specific traffic steering. One load balancer can now use different routing behavior for different locations. Each pool set can match a Cloudflare data center, country, or region. It then supplies the candidate pools and can apply its own steering policy, pool weights, and fallback…

Load Balancing now supports regional health

Cloudflare Load Balancing now supports regional health. Each Cloudflare region can make an independent health decision for a pool. When pool reachability differs by region, traffic can avoid an unreachable pool without removing it from service elsewhere. Configure regional health with the health_sources field on a pool. Set it to ["regional", "global"] to prefer regional health and use global hea…

Load balancing analytics now filters by pool name

Load balancing analytics now filters traffic data by pool name instead of pool ID, aligning the query behavior with the pool names displayed in the filter dropdown. Previously, the analytics pool filter queried by internal pool ID while displaying pool names in the UI dropdown. This mismatch caused filtering issues when pools shared similar names or when you expected results based on the visible…

Load Balancing health notifications now resolve automatically

Load Balancing health notifications are now stateful. When a pool or endpoint becomes unhealthy, the notification opens an incident in your alerting tool as before. When that same pool or endpoint recovers, the follow-up notification is matched to the original alert and resolves that incident automatically, so you no longer have to close it by hand. As part of this change, Load Balancing also sen…

See fallback pool traffic separately in load balancing analytics

Load balancing analytics now shows traffic served by your fallback pool separately from traffic routed to the same pool by normal steering. Previously, requests were grouped by pool name alone. If the pool acting as your fallback also received traffic through your steering policy, both appeared as a single series, so it was not obvious from the graph whether Cloudflare was still making health-bas…

Monitor Groups for Advanced Health Checking With Load Balancing

Cloudflare Load Balancing now supports Monitor Groups, a powerful new way to combine multiple health monitors into a single, logical group. This allows you to create sophisticated health checks that more accurately reflect the true availability of your applications by assessing multiple services at once. With Monitor Groups, you can ensure that all critical components of an application are health…

Steer Traffic by AS Number in Load Balancing Custom Rules

You can now create more granular, network-aware Custom Rules in Cloudflare Load Balancing using the Autonomous System Number (ASN) of an incoming request. This allows you to steer traffic with greater precision based on the network source of a request. For example, you can route traffic from specific Internet Service Providers (ISPs) or enterprise customers to dedicated infrastructure, optimize p…

Improvements to Monitoring Using Zone Settings

Cloudflare Load Balancing Monitors support loading and applying settings for a specific zone to monitoring requests to origin endpoints. This feature has been migrated to new infrastructure to improve reliability, performance, and accuracy. All zone monitors have been tested against the new infrastructure. There should be no change to health monitoring results of currently healthy and active pool…

New Account-Level Load Balancing UI and Private Load Balancers

We've made two large changes to load balancing: Redesigned the user interface, now centralized at the account level. Introduced Private Load Balancers to the UI, enabling you to manage traffic for all of your external and internal applications in a single spot. This update streamlines how you manage load balancers across multiple zones and extends robust traffic management to your private network…

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…
