Bunny.net launches CDN Load Balancer: $9.50/month in public preview

On 30 September 2026, Bunny.net opened the public preview of Bunny CDN Load Balancer, a traffic-balancing service across multiple origins built into the CDN's Pull Zones. It's aimed at anyone running several backends behind the same CDN zone — say, two primary regions plus a standby — who wants traffic priorities to remain valid even when an origin goes down.\n\n## How it works\n\nThe Load Balancer is a routing policy tied to the account, which can be linked to one or more Pull Zones. The service distributes HTTP(S) requests from the Pull Zones across the configured origins. Cached responses continue to be served directly from the edge, bypassing the load balancer entirely.\n\nOrigins are organised into groups by region, provider or function, with tiered priorities: primary groups share the current traffic load, while backup groups remain on standby. The pool can mix standard HTTP(S) servers, Bunny Storage, Edge Scripting and Magic Containers, so primary and standby capacity can use different types of backend.\n\nOn the failover side, the edge builds an ordered list of eligible destinations before contacting the first one, respecting priority tiers. After a 5xx response, only requests that are safe to repeat are retried: those with a body or using methods that modify data are not automatically replayed, to avoid duplicate orders or payments. The failover chain has a time limit, so a request doesn't get stuck bouncing between slow origins.\n\nOptional health checks monitor origins from across the entire bunny.net network: a degraded origin is excluded globally from rotation until it starts responding correctly again. Each edge also reacts to failures it encounters locally, even with active checks disabled. Sticky sessions are supported via an encrypted edge cookie for applications that need repeated requests to land on the same origin, though origin health always takes precedence.\n\n## Pricing and availability\n\nThe Public Preview is available at $9.50 per month per Load Balancer, including 50 million requests to the origin each month. Additional requests are billed at $0.65 per million. Requests served from the CDN cache are not counted. Sharing a Load Balancer across multiple Pull Zones means a single monthly fee and a single shared request quota.\n\nTo enable it, you need to create the policy, configure the origin groups with their respective priorities, then set the Pull Zone's origin type to Load Balancer. The official documentation covers routing, health checks, sticky sessions and API options.
