We are actively exploring potential mitigation options to address the sub-optimal routing and reduce the impact on affected origin fetch traffic. In parallel, we are working with the third-party provider to address the underlying geolocation issue. We will provide further updates as more information becomes available.
We are providing an update on the ongoing service disruption. The Middle East (UAE) Region (ME-CENTRAL-1) has suffered damage as a result of the conflict in the Middle East and is currently unable to reliably support customer applications. While some workloads continue to function normally, we strongly recommend customers migrate all accessible resources to other Regions and restore inaccessible resources from remote backups as soon as possible. Relevant billing operations are currently suspended while we restore normal operations in this AWS Region. This process is expected to take several months.
Core Cloud Services - Data Protection: Zscaler has detected an issue with its zscaler.net, zscloud.net Cloud. Customers with an HTTP/2 Header Profile applied via a URL Control Policy may experience intermittent login failures when accessing claude.ai. The HTTP/2 profile disrupts the authentication flow, which may prevent login from completing successfully. All other traffic forwarding and policy enforcement remain unaffected.We will continue to provide updates here as the investigation progresses.

Status changes and additional details will be posted there as they become available.Latest Update - Wed, 12 Aug 2026 06:54:30 UTCThe fix developed by Zscaler is currently undergoing validation.
