    January 16, 2017 1:01PM 1:13 PM 12 Ex Libris engineers have identified that during a maintenance activity that took place during the planned maintenance window, a misconfiguration on Load Balancer had taken place. This misconfiguration had caused the system to become unavailable.

    February 22, 2017 2:25AM 3:15AM 50 The cause of the undesirable UI behavior was due to a temporary error in the summon UI config service. The Summon UI 2.0 rely on a configuration repository in order to customize each customers experience. The error occurred during a restart of these services as part of routine work last Friday and the error was resolved as quickly as possible once it occurred.

    How is Summon 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    

    Where: 

      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.)
