Reliability Has Outgrown the Systems Supporting It
Service reliability has outgrown uptime checks and component-level tools, creating friction that slows response, increases toil, and wears teams down. Uptime checks can pass, high availability can be in place, and users still can’t complete basic actions. Pages load slowly, latency spikes, and requests stall — all without a single system flagged as down. Availability measures whether a service is running.
