Monitoring: Global Mitigation Applied by Zscaler

Zscaler has implemented a global fix to address the connectivity issues affecting multiple nodes (including Singapore, Chennai 2, and US-based data centers).

We have received initial confirmation from customers in both the US and APAC regions that service has been restored and they are now able to connect via their original primary nodes. Zscaler has also published an official update regarding this resolution on their Trust Portal: Zscaler Status Post 28871.

We are waiting the RCA from Zscaler engineering team

Monitoring: Expanded Impact to US Nodes & Escalation

The scope of this incident has broadened beyond the APAC region. We have now received reports of similar connectivity issues affecting Zscaler nodes in the US.

We have escalated this matter to senior Zscaler engineering leadership for an urgent, comprehensive investigation into what appears to be a multi-region disruption.

Current Status & Workarounds

While we await a global resolution from Zscaler, please continue to utilize the previously verified node failovers:

• India: Move from Chennai 2 to Hyderabad 1.

• APAC: Move from Singapore to Hong Kong 3 or Tokyo 4.

• US: We are currently identifying stable target nodes for US traffic and will provide specific recommendations shortly.

Our internal teams remain on high alert and are working alongside Zscaler to stabilize service globally.

Monitoring: Additional Impacted Node (Chennai 2) & Verified Workaround

Our ongoing investigation has confirmed that the disruption is not limited to Singapore. The Chennai 2 node (India) is also experiencing significant instability. We have successfully verified a workaround with impacted customers in the region.

Verified Workaround

If you are experiencing connectivity issues or tunnel drops on the affected nodes, please implement the following failovers:

• For India-based traffic (Chennai 2): Redirect tunnels to the Hyderabad 1 node. This has been confirmed to restore stable connectivity in live testing.

• For Singapore-based traffic: Redirect to Hong Kong 3 or Tokyo 4.

We remain in constant communication with Zscaler support as they work toward a permanent fix for the Singapore and Chennai data centers.

Monitoring: Multiple Impacted Nodes Identified (Singapore & Chennai)

Our ongoing investigation has confirmed that the issue is not limited to the Singapore node. We have identified that the Chennai 2 node (India) is also experiencing disruptions, contributing to the connectivity issues across the APAC region.

Recommended Workaround

To restore connectivity immediately, we suggest customers manually switch their traffic to one of the following stable nodes:

• Hong Kong 3

• Tokyo 4

We continue to work with Zscaler to resolve the specific issue in Singapore and will provide a final update once the node is stabilized.

Monitoring: Expanded Scope & Investigation

Our investigation has confirmed that the impact extends beyond the zscloud.net environment to include zscaler.net and other Zscaler clouds within the APAC region.

Zscaler has acknowledged our high-priority ticket, and we are working closely with their team while our internal engineers continue to pursue a parallel remediation path.

Monitoring: Investigation & Remediation in Progress

Zscaler has officially acknowledged our support ticket and is investigating the issue. Simultaneously, our internal engineering teams are evaluating potential remediation steps to restore service for APAC customers.

We will share more details as our joint efforts progress.
