fails: quotanational-idno cardRwrite-gated
| Free tier | 1 GB on registration and 20 GB after identity verification: '注册赠送1G存储。需要20G和S3、WebDAV、MCP需要使用国家网络身份认证app进行认证' unit GiB; metered on stored-bytes |
|---|---|
| Price | none stated |
| Per-object cap | Not published |
| Retention | Not published. State-backed academic infrastructure, so durability is high and shutdown risk low |
| Egress | The headline property: '不限流量、不限读写次数', no egress charge and no request metering, which is rare and matches the serving workload directly free_allowance: unlimited |
| Identity | national-id the 国家网络身份认证 app, a national digital identity. Registration alone yields 1 GB with no identity document |
| Limits | |
| Binding | write-gated Unlimited traffic and no request metering is exactly the right shape, and the gate is a national identity app. 1 GB unverified is 0.2% of the filter, so the identity decision is the only one that matters. |
| Interface | s3, webdav |
| Tooling | first-party S3 credentials with an AccessKey from 客户端访问, plus WebDAV and MCP. A rclone S3 mounting walkthrough exists and sccache over CSTCloud is documented for Rust builds |
| Composes with | 20 GB per verified identity and each data space is a separate bucket, so the only multiplier is identities. The identity is 国家网络身份认证, a national digital ID app, which makes it non-multiplicable for a user |
| Reliability | State-backed academic infrastructure, so durability is high. But a non-Chinese client cannot pass the national identity check, which caps them at 1 GB. Some seed records name the wrong operator and call it 中科院, the Chinese Academy of Sciences; the service is CSTCloud's, and the two are related but not the same institution, so both spellings are in the aliases |
| Notes | The most interesting shape in the topic and the most closed: unlimited traffic with S3, WebDAV and MCP is a user's workload exactly, and it is behind a national digital identity. This record is the second home for the provider, because the storage topic already carries cstcloud.json for its object-storage role. |
