This is something you can easily configure with our automatic retry function. We have an option to return a pre-configured response to the caller, and put the request in a queue to be retried until successful. This allows you to have a sustained outage while making sure all calls are eventually delivered.

Re-driving queue backlogs at services recovering from sustained outages ends in tears almost always. Tread carefully. :)

Typically people use two pools for circuit breaking, with the limit set lower on retries: https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overv...
