A subcloud is a subset of Internet & SaaS Private Service Edges or Public Service Edges, which are full-featured secure internet gateways that inspect all web traffic bi-directionally for malware, and enforce security, compliance, and next-generation firewall (NGFW) policies. Internet & SaaS Public Service Edges are deployed in Zscaler data centers (DCs) around the globe, so when your users move to a different location, they can access the internet from any device and the Internet & SaaS Public Service Edges will protect their traffic and apply your corporate policies.

You can edit a subcloud from the Subclouds page in the Admin Portal to temporarily disable the DCs under scheduled maintenance or DCs with capacity issues, trust incidents, site or region service issues, excessive latency, congestion, peering issues, etc.

To edit a subcloud:

1. Go to Infrastructure > Internet & SaaS > Traffic Forwarding > Subclouds.
2. Click the Edit icon next to the subcloud that you want to edit.

The Edit Subcloud window appears.

3. In the Edit Subcloud window:

• Under General Information, you can view the name of the subcloud.
• Under Data Center Schedule, you can view a list of the DCs configured for the subcloud, and select a DC from the list.
• Under Data Center Disabled Until (UTC Time), you can view and edit the date and time until which the selected DC is disabled. The time is displayed in Coordinated Universal Time (UTC). You can disable a DC for a maximum of two weeks.

4. Click Save and activate the change.
5. If you disable all the DCs in a country, a confirmation window appears. Click Confirm to continue.

After you edit the DC list for a subcloud, the Zscaler Client Connector traffic and PAC file users are redirected 15 minutes after the app policy push. To failover immediately, you can trigger DNS requests with app policy updates on Zscaler Client Connector. To learn more, see Understanding Subclouds.
