The importance of incident routing in site reliability engineering cannot be overstated, as it directly impacts response time, reduces confusion, and builds a reliable system. Good routing ensures that the right people are notified at the right time, shortening mean time to acknowledge (MTTA) and reducing noise by avoiding misrouted alerts. Clear routing also reinforces accountability by consistently sending alerts to the owning team, eliminating ambiguity around who should act. By embedding better context into alert processing and delivery, tools like incident.io Catalog can provide a central place to track services, teams, dependencies, and metadata, making it easier to automate routing with high accuracy. Effective routing is built on a foundation of clear, accurate service ownership, and by integrating observability platforms and refining rules over time, teams can make routing smarter and more reliable.
