DNS Test Findings for umd.net

This DNS lookup test ran on 2026-09-30 with an overall DNS response rate of 98.7% and a median DNS lookup time of 201 ms. The response rate fell slightly below the 99% threshold and median latency slightly above the 200 ms threshold, so the
umd.net 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
- 302 of 306 nodes returned a valid resolver response, leaving 4 unanswered lookups and an overall DNS response rate of 98.7%, below the 99% threshold.
- The overall median DNS lookup time was 201 ms, just above the 200 ms threshold, with p90 at 414 ms and p95 at 507 ms.
- Response rates by carrier were telecom 96.8%, unicom 100%, mobile 100%, and overseas 100%; the 4 unanswered lookups were on telecom.
- Only 1 unique response IP was observed across responding lookups, indicating low observed answer diversity in this run, which does not establish propagation correctness or a root cause.
Improvement recommendations
- The DNS response rate is 98.7%, 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 201 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.
These results describe this distributed test only and do not establish long-term availability, security, or a root cause.
