Nameservers we check
Each one gets a direct SOA query for hichina.com, a zone Alibaba Cloud serves authoritatively, once a minute.
| Nameserver | Status | Address | Latest | 24 h uptime |
|---|---|---|---|---|
| ns1.hichina.com | Operational | 139.224.142.123 | 196 ms | 100% |
| ns2.hichina.com | Operational | 139.224.142.124 | 216 ms | 100% |
Through public resolvers
Every minute each resolver is asked for a random name under hichina.com, so it can't answer from cache and has to reach Alibaba Cloud from its own network. If most of them still resolve the zone, Alibaba Cloud isn't marked down even when our own checks fail.
| Resolver | Status | Latest | 24 h success |

| Cloudflare | Resolves | 228 ms | 100% |
| Google Public DNS | Resolves | 237 ms | 100% |
| Quad9 | Resolves | 210 ms | 100% |
| OpenDNS | Resolves | 225 ms | 100% |
