What is posted availability specification for Windows server 2012? 2012R2?

Question

I am trying to put together a high availability solution and I want to know what the availability 'claim' of the individual components would be. What is the availability specification for Windows server 2012 and Windows Server 2012R2?(for example 99.9%
availability for the O/S itself). This would be in a non clustered or Load Balanced state. Just a single server running the O/S.

Hi,
SLA requirements determine how components such as storage, clustering, and backup and recovery factor into your organization.The term high availability is meaningless until you define how to measure it. IT shops measure high availability as the percentage of
time that systems are available, but the provider and consumer of high-availability services must agree on what constitutes availability and how the time is measured.
