Background for this topic.

Outage is a period when a system, network, application, or online service is unavailable or cannot perform its intended function. It may be planned maintenance or an unplanned disruption caused by equipment or software failure, misconfiguration, a dependency problem, natural hazards, or a denial-of-service attack. The tag generally concerns availability incidents, not every performance issue or security breach.

For security practitioners, an outage requires determining whether malicious activity contributed to the disruption while preserving relevant logs, network telemetry, and system state for investigation. Defenses include capacity planning, segmented and redundant architecture, tested failover and recovery procedures, and controls that limit the effect of DDoS traffic or compromised dependencies. Emergency changes made during recovery should be authorized and recorded, since they can create new vulnerabilities or affect data integrity. Clear incident ownership and communications help coordinate technical response without obscuring the cause or scope.
