Website Accessibility and Email Delivery Degradation in the US and EMEA Data Centers for a Public IP Subnet

Zscaler is aware of and currently investigating website accessibility and email delivery degradation associated with an external reputation-based filtering service affecting a public IP subnet range. The impacted IP subnet has been flagged by a third-party reputation provider, which is preventing access to certain websites and causing email delivery failures to some destinations. Zscaler is actively engaged with the third-party reputation provider to expedite removal of the impacted subnet. At this time, there is no estimated time to resolution; however, mitigation actions are being evaluated to reduce customer impact.Zscaler continues to closely monitor the situation and will provide updates as more information becomes available. For detailed updates, please check the Service Status section in your Zscaler customer support portal (CSP). Status changes and additional details will be posted there as they become available.
