DNS Test Findings for asia.teacher2040.com
- Tested
- Sep 20, 2026, 11:25 PM
- Completed probes
- 317/317
- DNS response probes
- 1 (0.3%)
- Average DNS lookup time
- 327 ms
Of 317 nodes, only 1 obtained a valid DNS result, giving a DNS response rate of 0.3 against a 99 threshold; the responding lookup took 327 ms, above the 200 ms threshold. This is a point-in-time observation from 2026-09-20 15:25 UTC.
asia.teacher2040.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
- Only 1 of 317 nodes returned a valid resolved result; 316 nodes were unanswered lookups, for an overall DNS response rate of 0.3.
- The telecom group had 130 nodes and a response rate of 0.8, with 1 node obtaining a result and a DNS lookup time of 327 ms.
- The unicom, mobile, and overseas groups each had a response rate of 0, with no resolved result and no usable DNS lookup time.
- Three resolved addresses were observed, which describes answer diversity only and does not establish whether resolution was correct or indicate a root cause.
Improvement recommendations
- The DNS response rate is 0.3%, 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 327 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.
