Making Deployments Safe at Meta: Health Checks for Continuous Change-Safety

The paper outlines Meta’s deployment time health check infrastructure, called Service Health Checker, which mediates the trade‑off between rapid release velocity and system reliability across thousands of heterogeneous services. It explains how check authors compose templated metric queries, thresholds, and workflow predicates, and how the system integrates with tiered and phased rollouts to trigger automatic rollback on regressions. The authors also discuss operational challenges that arose at scale—such as noise, alert fatigue, drift, and uncovered regressions—and the measurement, tooling, and default improvements they implemented to address these issues, concluding with lessons learned and future directions including AI‑assisted tuning.

Incident-Arena: Getting agents to the last nine of reliability

Incident‑Arena is a new benchmark for AI coding agents focused on production incident response, featuring 20 tasks derived from real‑world open‑source software. Each task deploys a production application on an ephemerally created Kubernetes cluster, injects faults at various layers, and applies a sustained load profile. The benchmark introduces functional verifiers that maintain system‑level metrics while ensuring safe repairs, and shows that current frontier models achieve below 64.3% across the tasks, highlighting challenges in diagnosis, repair, and regression safety.
