I’ve been working on a small system to understand how applications can stay up even when backends fail.The idea is simple:
instead of sending requests to a single backend, route them through a layer that can switch to another backend if something goes wrong.It:checks backend health (latency, errors)
avoids unhealthy servers
retries requests on another backend if neededIt’s designed as:a fast routing layer (Rust)
a simple control API (Python)
shared state via RedisOne thing I found interesting is that failover only works before the response starts — after that, switching isn’t possible.Still early and mostly an experiment to understand failover and reliability better. This begun as internal experiment, after recent region outages.Curious how others approach this problem in production systems.
Show HN: System that keeps apps running when a server or region goes down
An experimental system designed to ensure application uptime during backend or region failures by intelligently routing requests through a failover layer.
Product Positioning & Context
AI Executive Synthesis
An experimental system designed to ensure application uptime during backend or region failures by intelligently routing requests through a failover layer.
This system addresses a fundamental challenge in modern distributed systems: maintaining application uptime during backend or regional outages. The core concept of an intelligent routing layer that performs health checks, avoids unhealthy servers, and retries requests on alternative backends is critical for enterprise-grade reliability. The use of Rust for the routing layer emphasizes performance, while Python for the control API and Redis for shared state represent a common, robust technology stack. The explicit mention of 'recent region outages' highlights a direct market driver for such solutions. While presented as an experiment, this directly tackles a pervasive pain point for any business operating critical online services.
