Saatavuustaso

Saatavuustaso is a Finnish term that translates to "availability level" or "level of availability." It is commonly used in the context of IT service management and business operations to describe the degree to which a service or system is operational and accessible to its users.

The saatavuustaso is typically measured as a percentage over a specific period, often a month or a year. For example, a service with a saatavuustaso of 99.9% means that it is expected to be unavailable for no more than 8.76 hours per year. Higher saatavuustaso values indicate greater reliability and fewer disruptions.

Determining the saatavuustaso involves defining what constitutes an outage or unavailability. This can include scheduled maintenance, unexpected system failures, or network issues. The calculation often excludes planned downtime that is communicated to users in advance.

Establishing and monitoring the saatavuustaso is crucial for businesses to ensure that their critical services meet user expectations and support business continuity. Service level agreements (SLAs) often specify target saatavuustaso values, with penalties for failing to meet them. Achieving and maintaining a high saatavuustaso requires robust infrastructure, proactive monitoring, effective incident management, and well-defined disaster recovery plans.
