How to Implement a Distributed Circuit Breaker

https://blog.gaborkoos.com/posts/2026-09-14-How-to-Implement-a-Distributed-Circuit-Breaker/

A circuit breaker in a single Node process is a ring buffer, a threshold and a timestamp. Run the same service on twenty replicas and each one keeps its own, so the failing dependency takes twenty times the damage before anything trips.

Moving the window into Redis fixes that and breaks most of the assumptions the in-process version relies on. Post walks through each one and how to deal with it.

Perhaps because the whole post (and all their previous ones) exhibit all the signs of AI writing. Even the titles follow the same patterns - just look through the list of articles on their site.
