This DNS lookup ran on 2026-09-20 15:54 UTC. The overall DNS response rate was 13.9%, with only 44 of 317 nodes returning a valid result and 273 unanswered lookups. Two issues were detected: a low response rate and a carrier response gap.

youbuddydots.com 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 13.9%, well below the 99% reference threshold, leaving 273 nodes as unanswered lookups during this observation window.
  • Response rates differed by carrier: Unicom 24.7% and overseas 32.4%, versus Mobile 6.6% and Telecom 6.9%, a gap of about 25.8 percentage points between Mobile and overseas.
  • DNS lookup time among responding nodes was spread out, with p90 at 214 ms and p95 at 327 ms while the median and average stayed low, indicating most resolver responses were fast and a minority were slower.
  • Only 3 resolved addresses were observed, which describes answer diversity in this sample and does not establish whether resolution was correct or point to any root cause.

Improvement recommendations

  • The DNS response rate is 13.9%, below the 99% review threshold. Retest the unanswered probes and verify the authoritative DNS service, query type, and record only if failures persist.
  • China Mobile trails overseas by 25.8 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.
