In the 2026-09-30 observation, only 14 of 306 nodes obtained a valid DNS result, giving a 4.6% DNS response rate, well below the 99% reference threshold and a clear anomaly within this test.
8.130.152.233 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 4.6%, with 292 nodes returning no valid result; DNS lookup time was 6 ms at P50, 158 ms at P90 and 268 ms at P95.
- Response rates were 4.8% (6/125) on telecom, 5.4% (4/74) on unicom, 4.1% (3/74) on mobile and 3.0% (1/33) overseas, so unanswered lookups appeared on every carrier.
- Eight distinct resolved addresses were observed, which describes answer diversity in this run only and does not establish whether resolution was correct or indicate a cause.
- The node error count was 0, so the missing results reflect unanswered lookups rather than node errors.
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.
