  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: dns14.hichina.com (120.76.107.41): read udp 46.225.38.91:32913->120.76.107.41:53: i/o timeout.

    Serials differ
    SOA · The nameservers serve different versions of the zone: 2026081813 on dns14.hichina.com (2408:4009:501::22); 2026082509 on dns13.hichina.com (120.76.107.42), dns13.hichina.com (139.224.142.122); 2026082616 on dns13.hichina.com (39.96.153.42), dns13.hichina.com (139.224.142.112), dns13.hichina.com (47.118.199.202), dns14.hichina.com (120.76.107.51), dns14.hichina.com (47.118.199.201); 2026082617 on dns13.hichina.com (39.96.153.52), dns13.hichina.com (120.76.107.52), dns13.hichina.com (2408:4009:501::21), dns14.hichina.com (39.96.153.51), dns14.hichina.com (39.96.153.41); 2026082709 on dns14.hichina.com (139.224.142.121), dns14.hichina.com (139.224.142.111); 2026082815 on dns13.hichina.com (47.118.199.212), dns14.hichina.com (47.118.199.211). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

    Unusual SOA timers
    SOA · expire 1d is shorter than 7d; secondaries stop answering too soon when the primary is down. Current values: refresh 1h, retry 20m, expire 1d, negative TTL 10m.
