Reliability & Observability Initiative

Context

The team was capable but reactive. Incidents were resolved through heroics and tribal knowledge rather than instrumentation, and the same classes of problems recurred because root causes were never fully understood.

Approach

The initiative made reliability a discipline rather than a reaction:

• Consistent instrumentation. Standardizing on OpenTelemetry meant traces and metrics looked the same everywhere, so an engineer could navigate any service during an incident.
• SLOs and error budgets. Defining what “reliable enough” meant for each critical service turned reliability into a measurable, prioritizable concern.
• Blameless retrospectives. Making it safe to discuss failures honestly surfaced root causes early, while they were still cheap to fix.

Outcome

Incidents became survivable and, increasingly, rare. Engineers could go from “users are unhappy” to “this is the cause” in minutes instead of hours, and the culture shifted from blame to learning — which is what actually prevents the next outage.
