Reason For Outage (RFO) tracking

An RFO (Reason for Outage) is a body of knowledge for tracking known outages to learn from and to use as a reference when going back in time. This creates an actionable history of things that go wrong in production environments and can help in decision-making and resolution of potential issues.

Outages include

  • Resources that become unavailable. This could be due to many issues like network, infrastructure, faulty applications
  • Failed deployments
  • Manual application restarts necessitated by something going wrong

Outages do not include

  • Maintenance application/infrastructure restarts that are expected
  • Application downtimes due to deployments. This is not ideal however and can be avoided by adopting a different deployment strategy.
