Original: The Silent Outage: Monitoring What You Can't See

Short summary

Silent outages — where dashboards stay green but users get a broken experience — are the hardest to catch. The author identifies three patterns: CDN-cached errors, partial feature breakage, and stale data pipelines. Defenses include synthetic user journeys, data-freshness alerts, business-metric monitoring, and error-budget burn-rate tracking. The ultimate silent outage is user churn from quiet frustration, only visible in usage graphs weeks later.

  • •Silent outages include CDN-cached 500s, partial feature failures, and frozen data pipelines
  • •Defenses: synthetic journeys, data-freshness alerts, business-metric SLIs, error-budget burn rate
  • •The worst silent outage is churn from users who gave up — monitor conversion and DAU as SLIs

Generated with AI, which can make mistakes.
