    Ex Libris engineers found that the issue was caused by a high amount of packet loss on the Firewall. The issue was triggered after a firmware upgrade of the firewall and the packet loss had been identified as a mismatch between a configuration and the license on the firewall. The issue was resolved by removal of the problematic configuration.

    How is Primo Uptime Calculated?

    The uptime calculation is based on the following calculation (as defined in the Alma 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 12 months


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