Risk Warning: Yinyun and Linked-Operator Service Failures
As of July 1, 2026, Yinyun is on this site's provider-exit warning list. It shares an operator with Naiyun, CAC, and OKAC. Naiyun was confirmed closed, and CAC and OKAC showed website, node, customer-support, or management-response failures.
Current risk notice
Yinyun, Naiyun, CAC, and OKAC share an operator. With Naiyun closed and correlated failures appearing across related projects, Yinyun users should stop new purchases and renewals and preserve plan, payment, subscription, and support records.

Historical product claims
These points describe what Yinyun advertised before the warning. They do not indicate current availability.
Dual modes
- Custom client with one-click connection and advertised unlimited traffic.
- Universal subscription compatible with Clash, Shadowrocket, and V2Ray, with no device-count limit advertised.
“Magic node” routing
The provider advertised server-side routing for Netflix, Disney+, YouTube, ChatGPT, and other services without client-side rules.
Dedicated-line architecture
The old material claimed IPLC, IEPL, and BGP routes, more than 100 nodes across 30+ countries and regions, 99.9% availability, and intelligent path selection.
Streaming and AI services
It advertised Netflix, Disney+, HBO Max, Amazon Prime Video, YouTube Premium, TikTok, ChatGPT, Claude, and Midjourney.
Peak-hour performance
It also claimed automatic congestion avoidance and smooth 4K video during evening peaks. Current service-risk evidence supersedes these marketing claims.
Client and evidence steps
If you previously used the custom client, export or screenshot the account, plan, and subscription records before removing access.

Frequently asked questions
Should users buy Yinyun now?
No. Stop new purchases and renewals. Preserve records instead of putting more money into a service under a correlated-operator warning.
What should existing users do?
Back up the subscription and payment evidence, disable automatic renewal, arrange an unrelated backup provider, and monitor the website, nodes, tickets, and official notices.
Why assess Yinyun together with Naiyun, CAC, and OKAC?
The source identifies the same operating entity. Failures across websites, nodes, support, and management under one operator increase correlated risk.
Conclusion
Yinyun formerly promoted dual client modes and server-side routing. Current risk control matters more:
- Naiyun under the same operator is confirmed closed.
- CAC and OKAC showed multiple failures.
- Yinyun is therefore under a correlated provider-exit warning.
- Users should stop purchases and renewals and preserve evidence.
Do not choose Yinyun as a primary or backup service now. Read the Yinyun provider-exit warning and choose an operator without the same linked risk.
