Classificação de severidade da interrupção do Uptime Institute

The Outage Severity Rating (OSR) was developed by Uptime Institute to help the digital infrastructure industry better distinguish between a service outage that threatens the business and an interruption that has little or no impact.

Uptime Institute's Intelligence group studies publicly reported outages to understand what causes unplanned downtime and the effects of service interruptions. The number of outages reported by the media has climbed steadily year on year, from 27 in our first year of reporting (2016) to 163 in 2019.

A OSR do Uptime Institute ajudará a comunidade de infraestrutura digital e datacenter a entender e articular melhor as interrupções de serviço no contexto de como cada incidente afeta os negócios.

The OSR provides infrastructure practitioners a common lexicon to use in forming their own service delivery capacity strategies and describing their own outages in terms of business impacts, rather than referencing outages based upon the number of physical infrastructure components involved.

Uma métrica para classificar a severidade e o impacto de interrupções

Although there are various ways to categorize the mission criticality of various systems as a planning tool for disaster recovery and availability/redundancy investments, there is no Beaufort scale for measuring the severity/impact of outages.

Essa classificação é claramente útil. For example, the effect of losing access to a human resources system for two weeks might be frustrating but negligible, even in large organizations, while a 5-minute loss of a currency trading system could be near catastrophic to the business.

For classifying the impact of publicly reported outages, Uptime Institute has created a five-level Outage Severity Rating as outlined below.

As infraestruturas híbridas fornecem serviços em um nível de capacidade projetada, com base em todos os componentes disponíveis. Historically, use of the term “outage” reflected a binary state of service delivery. As the IT industry continues to leverage hybrid infrastructure designs, the definition and scope of outages must change as well. This rating method provides a lexicon to quantify outages and their impact to business.

“A conscientização pública sobre interrupções está se tornando mais pronunciada à medida que o número aumenta ano após ano. Na maioria dos casos, achamos difícil entender a verdadeira natureza e magnitude da interrupção, pois a maioria dos profissionais ainda caracteriza a severidade de uma interrupção com base na quantidade de equipamentos de infraestrutura física afetados.”
