    As part of our continuous efforts to ensure the availability, stability, and security of our Private Cloud services, we recently performed an upgrade to our load network infrastructure. During this process, a temporary misconfiguration occurred due to a software bug, resulting in a network disruption. 

    Upon identification, our network engineering team promptly implemented a mitigation strategy provided by our vendor to manually correct the misconfiguration. Normal service has been restored. 

    • The Network team Implemented a temporary protocol adjustments prior to system upgrades to avoid potential known bugs.

    High CPU usage on one of our Network devices caused disruptions to the services in the Data Center. Our engineers took some re-routing measures to resolve the issue.  

    During this disruption we have experienced a technical issue that prevented posting our updates to you via the Status Page, our live communication tool. We have taken immediate measures to assure its stability onwards and will continue to do so as we value transparency and real time updates. We apologies for this experience.

    • Clarivate’s Network team is working with the vendor to understand the sudden increase in usage and to ensure efficient CPU usage and improved performance. 

    • Clarivate’s network team creates some optimization on the device’s configuration.

    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 by 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.)
