Nameservers we check
Each one gets a direct SOA query for microsoft.com, a zone Azure DNS serves authoritatively, once a minute.
| Nameserver | Status | Address | Latest | 24 h uptime |
|---|---|---|---|---|
| ns1-39.azure-dns.com | Operational | 150.171.10.39 | 8 ms | 100% |
| ns2-39.azure-dns.net | Operational | 150.171.16.39 | 5 ms | 100% |
| ns3-39.azure-dns.org | Operational | 13.107.222.39 | 5 ms | 100% |

Through public resolvers
Every minute each resolver is asked for a random name under microsoft.com, so it can't answer from cache and has to reach Azure DNS from its own network. If most of them still resolve the zone, Azure DNS isn't marked down even when our own checks fail.

| Google Public DNS | Resolves | 6 ms | 100% |
