The period of time that equipment is not operational, whether as a consequence of an unanticipated equipment failure (such as a problem or damaged part) or scheduled downtime, is referred to as equipment downtime (like necessary downtime for preventive maintenance). Equipment downtime can be divided into two categories: planned downtime and unscheduled downtime.
Planned downtime is usually included in the equipment warranty. The manufacturer may recommend specific procedures for maintaining the equipment; if these procedures are followed, then the downtime will be minimal and short. For example, a piece of rotating equipment such as a fan or motor might need to be taken off-line every few years for its bearing components to be inspected and replaced if necessary.
Unscheduled downtime occurs when a unit fails or produces substandard output despite following recommended procedures for maintenance and operation. Unscheduled downtime may be caused by any number of problems with the equipment itself. For example, a fan blade could break off due to material fatigue, causing the unit to lose some of its capacity until it can be repaired or replaced. Or, a circuit breaker might open during testing of the system's electrical connection, indicating that there is a problem with the power supply.
In general, more expensive machines have less downtime than less expensive ones.
Scheduled Downtime refers to the total number of hours in any month when each piece of equipment is down owing to preventative maintenance, scheduled maintenance, infrastructural difficulties, or any other condition that is not attributed to SI's (or service provider's) failure to exercise due care in...
Scheduled Downtime means the estimated number of hours that a facility will be unavailable for its intended purpose during an expected period of maintenance. Scheduled downtime may affect application services, space facilities, research instruments, etc. The term includes both public and private entities that use equipment or facilities for scientific purposes.
Scheduled Downtime is calculated by multiplying the total number of hours in any month by the percentage of time that the facility is unavailable. For example, if a facility is unavailable for 100 hours per month, its Scheduled Downtime is 12,000 hours per year.
Unscheduled Outages occur when equipment fails while it is being maintained. Examples include equipment malfunction during preventive maintenance or failure of electrical components due to age-related problems. These events can cause the facility to be unavailable even though no scheduled downtime has been incurred. Unscheduled outages should be reported as they can have an impact on the reliability of the facility's operation.
The phrase "downtime" refers to periods when a system is not available. This is often the consequence of the system ceasing to function as a result of an unanticipated occurrence or scheduled maintenance (a planned event). The phrase is widely used to refer to networks and servers. A network outage may prevent devices on the network from communicating with each other, while a server outage prevents systems using that server from obtaining information from it.
Technology downtime can be classified into two main types: planned and unplanned. Planned downtime is assumed to have occurred if no unexpected events have happened during a schedule change or maintenance window. Unplanned downtime occurs if an unexpected issue arises that causes a delay to the maintenance schedule. For example, if a part needs replacing but the supplier is out of stock then the site will experience unplanned downtime.
Unplanned downtime can be further divided into three categories: remediation, recovery and preventive maintenance (PM). Remediation actions are taken after an incident has been detected but before normal service has been restored. These may include fixing a broken device or component, clearing blocked cables or plumbing, or any other action needed to restore service. Recovery means returning a system or application to a known working state, either manually by staff members or automatically by software. For example, this might mean restoring data from a backup copy or removing a failed device from its docking station and shipping it back to the manufacturer for repair.
