Zscaler maintenance

Dear Customer, 

In accordance with the Zscaler Service Continuity Policy and as previously announced via email notification and Trust on June 15, 2026, we would like to remind you of the upcoming data center expansions at the locations listed below. These would be effective anytime on or after August 14, 2026.

Please update your firewall policy rules and any upstream access control lists to allow the new IP address ranges to avoid any service disruption. We recommend that you add the IP address ranges listed in the "Zscaler Aggregate IP Address Ranges'' section of the CENR page to your access lists, firewalls, and application allowlists to avoid service disruption. The IPs from these ranges can be put in use by Zscaler for Web and Internet Application communication and dynamic service resolution.
