Zscaler maintenance

Dear Zscaler Customer,

In accordance with Zscaler Service Continuity Policy and per email notification sent on July 1, 2026, we would like to notify you of the upcoming data center expansions at the locations listed below. These would be available anytime on or after August 30, 2026; 60 days or more from the date the first email notification is sent.

Please update your firewall policy rules and any upstream Access Control Lists (ACLs) 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 pages (refer applicable links below) to your access lists, firewalls, and application allow lists 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.
