Nameservers we check
Each one gets a direct SOA query for rwth-aachen.de, a zone RWTH serves authoritatively, once a minute.
| Nameserver | Status | Address | Latest | 24 h uptime |
|---|---|---|---|---|
| zs1.rz.rwth-aachen.de | Operational | 134.130.4.9 | 109 ms | 100% |
| zs2.rz.rwth-aachen.de | Operational | 134.130.5.9 | 103 ms | 100% |
Through public resolvers
Every minute each resolver is asked for a random name under rwth-aachen.de, so it can't answer from cache and has to reach RWTH from its own network. If most of them still resolve the zone, RWTH isn't marked down even when our own checks fail.
| Resolver | Status | Latest | 24 h success |
|---|---|---|---|
| Cloudflare | Resolves | 114 ms | 100% |
| Google Public DNS | Resolves | 98 ms | 100% |
| Quad9 | Resolves | 2 ms | 100% |
| OpenDNS | Resolves | 92 ms | 100% |
