| Free tier | A free cloud server at 1 core, 1 GiB RAM, 5 Mbps bandwidth and a 10 GiB data disk, on BGP multi-line with an independent IP address, plus a free 免备案 (no ICP filing) service for domains pointed at it. The vendor states it has run the free product for eighteen years. Activation requires a mobile-number account and 实名认证 (real-name verification) that costs CNY 0.3. The first activation is 24 hours only. A renewal is earned by posting on a recommended site and submitting a screenshot for review, and each approved extension adds 5 days. A server that expires and is re-opened costs CNY 2. unit hours; metered on wall-clock; kind not stated |
|---|---|
| Price | none stated |
| Binding | none no binding constraint identified |
| Identity | national-id A mobile-number account plus real-name certification: the vendor page states '通过手机注册账号' (register an account by mobile phone) and '实名认证，实名认证需要花费0.3元钱' (real-name certification costs CNY 0.3), quoted in evidence row 1. The kind is national-id because the gate that fails is the real-name check, not the email. |
| Egress | two network models: traffic-added, where the package traffic is issued per period and the port is throttled after exhaustion, and unlimited-traffic, where a lower fixed bandwidth is priced directly |
| Interface | unknown inferred from the tooling the provider documents; not probed |
| Tooling | not stated |
| Composes with | not established |
| Reliability | no reliability event recorded |
| Notes | no open question recorded The provider name was recorded only in Chinese and the promoter's ASCII fold emptied it; the ASCII transliteration is used here and the original is in the free-tier sentence. |
