877a.cn 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
- The overall DNS response rate was 99.4%: 313 nodes returned a response and 2 did not, a small share of unanswered lookups.
- Response rates stayed at or above 98.5% across carriers: telecom 98.5%, unicom 100%, mobile 100%, overseas 100%, with no broad pattern of unanswered lookups.
- Median DNS lookup time was 149 ms overall, with P90 at 376 ms and P95 at 509 ms, so tail timing was clearly higher than the median.
- Overseas nodes showed a median lookup time of 373 ms and average of 394 ms, a 348 ms gap versus the mobile median of 25 ms, above the 300 ms threshold.
Improvement recommendations
- overseas has a P50 latency gap of 348 ms versus China Mobile. Compare routes from both groups and verify that the gap narrows after any routing change.
