How we score SLA compliance

Each vendor is compared against its publicly stated SLA target. "Meeting" means the actual 30-day uptime is at or above the target; "Breaching" means below. Delta is the gap (positive = exceeding by that much; negative = breaching by that much). Breach hours convert the percentage gap into the actual hours of unmet SLA over the period.
