Is Zscaler Down? Real-Time Status and Service Monitoring

person By: Monitoring team
update Last updated: May 4, 2026, 8:52 AM UTC

Zscaler is a leading cloud-native security platform that provides automated threat protection and secure access to applications for enterprises globally. As a critical component of modern Zero Trust architectures, any downtime can immediately disrupt secure internet access and internal application connectivity for millions of corporate users.

Currently, based on our real-time global monitoring network, the status of Zscaler is operational. The vast majority of the community reports seamless functionality. If you are uniquely facing issues where Zscaler is not loading, we recommend checking your local Wi-Fi, clearing your browser cache, or restarting your application, as global servers appear to be completely healthy.

The Consequences of a Zscaler Connectivity Failure

When Zscaler experiences a service disruption, users typically encounter 'Gateway Timeout' errors, inability to authenticate through the Zscaler Client Connector, or a complete loss of internet connectivity if 'Fail Closed' policies are active. This halts business operations by preventing access to essential SaaS tools and private cloud resources.

Our live map aggregates thousands of these specific complaints in real-time. If you see elevated bars on the chart above, the Zscaler down detector algorithm has successfully identified severe backend degradation that aligns with these exact symptoms.

Latest Zscaler Outage Reports and User Feedback

By analyzing the past 24 hours of telemetry, we observed roughly 0 outage complaints globally. Factoring in these connectivity drops, the calculated Zscaler uptime over the last day rests at 100.00%.

Incredibly, there have been absolute zero significant outage spikes recorded recently. This flawless historical chart suggests a highly stable baseline performance, meaning their engineers are currently successfully mitigating any backend stress or traffic loads.

How to Resolve Zscaler Connection and Authentication Issues

When the global status reads 'Operational' but the app still crashes on your device, the problem is local. Try these simple fixes to restore your Zscaler connection:

  • Restart the Zscaler Client Connector: Open the Zscaler Client Connector (ZCC) app on your desktop, navigate to the 'More' menu, and select 'Restart Service' to re-establish the encrypted tunnel and refresh your security policy.
  • Re-authenticate your User Session: If you are stuck in a login loop, try logging out of the Zscaler app entirely and logging back in to ensure your SAML or SCIM credentials are valid and properly synchronized with your identity provider.
  • Network/DNS Check: Verify that your local network isn't blocking Zscaler's required ports (usually 80 and 443) and ensure your DNS settings aren't preventing the client from resolving the nearest ZIA Public Service Edge.

Our Methodology for Tracking Zscaler's Global Infrastructure

We don't wait for PR departments to admit there's a problem. By automatically tracking the real-time velocity of Zscaler down reports across social networks and the web, we can publish outage alerts long before official sources acknowledge the failure.

Our intelligent backend systems constantly cross-reference the incoming volume of these Zscaler down reports against a historical background baseline curve. When the live data deviates significantly and crosses a mathematical threshold, our website instantly flips the status from green to red, publishes the warning on this page, and logs the precise minute the downtime commenced. This guarantees that you are receiving the fastest, most unbiased, and most accurate outage intelligence available anywhere on the internet today.

Frequently Asked Questions
