Nameservers we check
Each one gets a direct SOA query for ultradns.com, a zone UltraDNS serves authoritatively, once a minute.
| Nameserver | Status | Address | Latest | 24 h uptime |
|---|---|---|---|---|
| ns61.ultradns2.com | Operational | 204.74.104.61 | 22 ms | 100% |
| ns61.ultradns2.org | Operational | 204.74.106.61 | 31 ms | 100% |
Through public resolvers
Every minute each resolver is asked for a random name under ultradns.com, so it can't answer from cache and has to reach UltraDNS from its own network. If most of them still resolve the zone, UltraDNS isn't marked down even when our own checks fail.
| Resolver | Status | Latest | 24 h success |
|---|---|---|---|
| Cloudflare | Resolves | 7 ms | 100% |
| Google Public DNS | Resolves | 23 ms | 100% |
| Quad9 | Resolves | 24 ms | 100% |
| OpenDNS | Resolves | 21 ms | 100% |
| AdGuard DNS | Resolves | 24 ms | 100% |
