Outages

An outage is a temporary loss of service of a Configuration Item. It can be the result of planned maintenance or operational failure.

Outage classes

Outages fall into different classifications:

Planned (and approved) outages
Degraded service
- Partial loss of service
- Slow response time
- Intermittent interruptions
Total loss of service

Availability criteria should specify what the maximum outage threshold is on a monthly basis. For example, you can choose a metric based on the required percentage of up time, or the maximum time allowed for an outage, when you define an availability Service Level Target.

Planned outages

A planned outage is usually the result of a routine maintenance schedule, upgrade action, or faulty equipment replacement. Incidents, change requests, and change tasks can generate outage records. The change request and task records show scheduled downtime. Incident, change request, and change task records have a checkbox to specify if the Configuration Item is out of service.

Note: Some planned outages may fall within pre-defined service windows when the outage does not count against availability metrics.
