Period of time that a service, system, process or business function is expected to be unusable or inaccessible which has a high impact on the organisation, compromising the achievement of the organisation’s business objectives. An outage is different to ‘downtime’ where process or system failures happen as a part of normal operations, and where the impact merely reduces the short-term effectiveness of process.
