This DNS lookup test for oktamail.amd.com ran on 2026-09-30. Only 11 of 305 nodes obtained a valid result, giving a 3.6% DNS response rate, a 471 ms median DNS lookup time and a 2193 ms tail. Ten distinct resolved addresses were observed, y
oktamail.amd.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 3.6%, with 294 nodes not obtaining a valid result, recorded as unanswered lookups during this test window.
- DNS lookup time reached a 471 ms median, 1600 ms at P90 and 2193 ms at P95, all above the reference thresholds applied in this test.
- By carrier, mobile nodes produced no resolver response; telecom and unicom were near 4% and overseas 9.4%, each with a small number of observable samples.
- Unicom showed a 1600 ms median DNS lookup time against 54 ms for overseas, a gap of about 1546 ms observed between carriers.
Improvement recommendations
- The DNS response rate is 18.2%, below the 99% review threshold. Retest the unanswered probes and verify the authoritative DNS service, query type, and record only if failures persist.
- 2 DNS responses contained no observed resolved address. Repeat the same query type and, if empty answers persist, verify the authoritative record and resolver response.
