1. What is a subcloud in Zscaler?
A logical grouping of ZIA Public or Private Service Edges within a geographic or
customer-specific region to optimize routing and scalability.
2. Why does Zscaler use subclouds?
To improve performance by directing user traffic to a local/regional set of
service edges with lower latency and reduced congestion.
3. How does Zscaler assign users to a subcloud?
Based on login location, IP geolocation, and DNS proximity during the
authentication and Central Authority handshake.
4. What PAC variable ensures clients connect to their assigned subcloud?
gateway.subcloud.zscaler.net
5. What’s the difference between gateway.zscaler.net and
gateway.subcloud.zscaler.net?
gateway.zscaler.net = Global resolution (default service edges)
,gateway.subcloud.zscaler.net = Regionally assigned service edges based on login
or policy
6. What could happen if a user configured to use subclouds is directed to
gateway.zscaler.net?
They may be routed to a non-optimal service edge, resulting in increased
latency or session inconsistency.
7. What role does the Central Authority (CA) play in subcloud routing?
The CA dynamically assigns users to a subcloud and updates the login and
policy distribution to those specific service edges.
8. What is subcloud stickiness?
The tendency for a user to remain assigned to a specific subcloud until a major
condition (location/IP change) triggers reassignment.
9. How does Zscaler handle subcloud failover?
If the assigned subcloud becomes unavailable, the CA reassigns the user to a
backup subcloud and may update PAC file behavior (if dynamic PAC is used).
10. Can multiple subclouds be assigned to a single organization?
Yes, especially in large or global orgs with many offices—each location may
resolve to its nearest subcloud.
Operations & Troubleshooting
, 11. How can an admin verify which subcloud a user is connected to?
By checking login logs in the ZIA Admin Portal or examining the resolved PAC
file hostname.
12. What are signs that a user is assigned to the wrong subcloud?
Latency is higher than expected
User is routed to a geographically distant service edge
Login delays or intermittent policy mismatches
13. How do SD-WAN devices or GRE tunnels interact with subclouds?
They should be configured to point to the correct gateway.subcloud.zscaler.net
hostname to ensure alignment with the assigned subcloud.
14. Is subcloud architecture applicable in ZPA?
No. Subclouds are specific to ZIA. ZPA uses App Connectors and Central
Authority routing for private access.
15. What happens during a Zscaler data center maintenance event in a subcloud?
The CA may reassign users to a nearby subcloud and redirect traffic
dynamically through updated PAC behavior or ZCC reconfiguration.
1. What are the main methods to forward traffic to ZIA?
Zscaler Client Connector (ZCC)
GRE Tunnels
