    A service disruption was experienced due to a problem with the APAC Datacenter ISP.

    Ex Libris cloud engineers worked closely with the ISP and followed up with him until the issue was resolved.

    December 20, 2021 12:44 PM 14:09 PM 85

    Due to a malfunction in one of the network devices, our services from the Singapore datacenter become unavailable for customers.

    Once the issue was identified, we enabled the redundant network device to bring the service back up.

    How is Uptime Calculated?

    The uptime calculation is based on the following calculation (as defined in the 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.)
