The service level agreement (SLA) is defined in terms of a _support window_. The support window is the period of time that an HDInsight cluster version is supported by Microsoft Customer Service and Support. If the version has a _support expiration date_ that has passed, the HDInsight cluster is outside the support window. The support expiration date for a specified HDInsight version X (after a newer X+1 version is available) is calculated as the later of:
