This DNS lookup test covered 298 nodes with an overall DNS response rate of 99.7% and a median DNS lookup time near 0 ms. The detected issue list is empty, so no clear anomaly requiring a change was found.
github.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
- 297 of 298 nodes returned a valid resolver response; one node produced no result, giving an overall DNS response rate of 99.7%.
- Telecom, Unicom, and Mobile each showed a 100% response rate, while overseas nodes showed 96.6% with one unanswered lookup.
- Median and average DNS lookup times were near 0 ms across carriers, with Unicom averaging about 1 ms; timing differences were minimal.
- Eighteen distinct observed resolved addresses were recorded, reflecting answer diversity in this test only.
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.
