    This DNS lookup for sg03.ctcxianyu.co ran on 2026-09-20 15:47 UTC. All 317 nodes returned no valid DNS result, giving a 0% DNS response rate, below the 99% threshold and worth attention.

    sg03.ctcxianyu.co DNS lookup performance by network

    DNS response rate counts probes with a DNS response and measured lookup time. P50 is the time at or below which half of responding lookups completed; a response need not contain an address and does not establish propagation or poisoning.

    Key findings

    • All 317 nodes produced no valid DNS response; respondedNodeCount is 0 and the DNS response rate is 0%, far below the 99% threshold.
    • Telecom, Unicom, Mobile and overseas all show a 0% response rate across 130, 77, 76 and 34 nodes respectively, with no comparable carrier difference.
    • With no resolver response at all, DNS lookup time percentiles and averages cannot be computed, and the observed resolved address count is 0.
    • nodeErrorCount is 0, so nodes did not report errors, yet none of the 317 nodes obtained the valid result defined for this test.

    Improvement recommendations

    • The DNS response rate is 0%, below the 99% review threshold. Retest the unanswered probes and verify the authoritative DNS service, query type, and record only if failures persist.

    These results describe this distributed test only and do not establish long-term availability, security, or a root cause.
