    How is Uptime Calculated?

    The uptime calculation is based on the following calculation (as defined in the campusM Service Level Agreement):

    "Uptime" means the total period in minutes during which the Service is available for access and use during this period.


    Uptime Percentage” means Uptime expressed as a percentage, calculated in accordance with the following formula:   


     Uptime Percentage = X /(Y–Z) × 100    


      X = Uptime

      Y = Last 12 months period

      Z = The duration (in minutes) of any SLA Exclusions* during these 9 months


    *SLA exclusions are defined in the contract SLA (e.g. Scheduled maintenance, etc.)
