Availability counts operational or degraded time as available, averaged equally across all monitored components. Partial outages count as half downtime and major outages count in full, scheduled maintenance is excluded from the calculation, and periods with no recorded status are counted as available rather than assumed down. Each component is tracked independently to give you a clear picture of overall service reliability.
