Of 317 nodes, only 2 obtained a valid DNS result, giving a 0.6% DNS response rate. Median DNS lookup time was 630 ms and the tail reached 1057 ms. Mobile and overseas nodes returned no resolver response, while unicom and telecom each had on

poctechcloud.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 0.6%, with 315 nodes producing no valid result during this observation window.
  • Median DNS lookup time was 630 ms and P95 was 1057 ms, both above the reference thresholds used for this test.
  • The unicom node showed a DNS response time of 1105 ms versus 154 ms on telecom, a gap of roughly 951 ms.
  • Mobile and overseas nodes recorded zero responses, so no resolver response or observed resolved address appeared there.

Improvement recommendations

  • The DNS response rate is 0.6%, below the 99% review threshold. Retest the unanswered probes and verify the authoritative DNS service, query type, and record only if failures persist.
  • P50 reached 630 ms, above the 200 ms review threshold. Repeat the same probes at a different time and investigate the relevant resolver service and query path only if the elevated median persists.
  • P95 reached 1057 ms, above the 1000 ms review threshold. Retest the slow probes and compare their routes or service stages before changing production configuration.
  • China Unicom has a P50 latency gap of 951 ms versus China Telecom. Compare routes from both groups and verify that the gap narrows after any routing change.
