- Unanswered lookups appeared on telecom and overseas nodes: telecom 97.7% and overseas 97.1%, while unicom and mobile both reached 100%.
- Median DNS lookup time was near 0 ms overall; overseas nodes averaged 36 ms with a P90 of 37 ms, clearly above the other carriers.
- Only 2 unique response IPs were observed, which describes answer diversity in this run only and does not establish resolution correctness or propagation.
Improvement recommendations
- The DNS response rate is 2.8%, below the 99% review threshold. Retest the unanswered probes and verify the authoritative DNS service, query type, and record only if failures persist.
- overseas trails China Telecom by 56.1 percentage points in response rate. Retest both groups with the same probe set, then investigate the affected network or endpoint only if the gap repeats.
These results describe this distributed test only and do not establish long-term availability, security, or a root cause.
