Bunny.net: Burrow Smart Routing in GA, 50 GB included then $0.06/GB

Bunny.net announced on 17 September 2026 on its official blog the general availability release of Burrow Smart Routing, the dynamic routing engine integrated into Bunny Optimizer. The feature had been in public preview since October of the previous year.

What Burrow does

Burrow handles uncached requests: API calls, custom responses, e-commerce checkouts. When the direct path to the origin is slow, Burrow is a continuously active and self-optimising routing engine, integrated into bunny.net's network infrastructure, that monitors global network conditions across 119 datacentres in 77 countries, analyses latency and status signals in real time, and selects the optimal path to the origin for each request, avoiding congestion, packet loss, outages and cable cuts. Traffic served from the cache remains outside this mechanism.

During the preview phase the company rewrote the routing engine to identify useful paths more quickly and to be more selective about when it makes sense to divert traffic. Among the new features introduced in this release is Active Origin Probing: the network can now actively query regions near the origin to measure alternative paths even when the site hasn't yet generated enough traffic to uncover better routes on its own, useful for smaller sites or those with audiences concentrated in a single geographic area.

Pricing and thresholds

With the general availability release comes the final pricing. Each Bunny Optimizer subscription includes 50 GB per month of uncached traffic routed by Burrow, beyond which additional traffic is billed at $0.06 per GB. Traffic served from the cache does not count towards this threshold.

The company notes that billing for additional Burrow traffic begins on 17 October 2026: until that date usage remains free for all Optimizer users, who can therefore test the feature without unexpected costs.

How to enable it

To enable Burrow, open the Pull Zone, activate Optimizer if not already active, go to the Burrow tab and toggle Burrow Smart Routing on. For Active Origin Probing, first configure the origin to respond correctly on the /.well-known/bunny-burrow-probe.txt path, then activate the corresponding toggle in the same section.

Optimizer statistics show how many requests were optimised by Burrow and an estimate of time saved for each Pull Zone.
