F.12:7.1 - Availability share

Promise: availability is at least 99.9% for a calendar month. Delivery Work: the defined service-delivery occurrences or population during that month. Evidence: observations and measurement results for the promised availability characteristic. A System performs evaluation Work; its A.6.1 application binds the in-scope values and returns the declared result. If the observation model already concerns the promised characteristic, there is no proxy relation. If synthetic probes instead indicate a different user-experience characteristic, name the exact indicator relation, its defining or testing pattern, uncovered regions or degradations, and the evidence-use boundary; otherwise stop with missing-governor.
