"The Zscaler cloud security platform is built using multiple distributed clouds to optimize for performance and resiliency. This specific issue only impacted one of multiple clouds and only one of Zscaler's service offerings within that cloud. Customers using other Zscaler services within that or other clouds were not impacted. We are also working closely with customers that were impacted. As of 9 am PDT, the vast majority of customers are fully recovered with post validation checks to be completed within 30-60 minutes." - Zscaler.
