DNS Test Findings for zco.cc
- Tested

This DNS lookup test on 2026-10-24 found an overall DNS response rate of about 1%: only 3 of 297 nodes returned a valid result, with a median DNS lookup time near 375 ms. Overseas nodes returned no response.
zco.cc 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 3 of 297 nodes returned a valid resolved result, giving a DNS response rate of about 1%, well below the 99% reference threshold; the other 294 nodes were unanswered lookups.
- Among responding lookups, the median DNS lookup time was 375 ms, above the 200 ms reference threshold; telecom, unicom and mobile medians were 349, 375 and 377 ms respectively.
- All 29 overseas nodes returned no response, so no usable DNS lookup timing was recorded for that group.
- All responses shared a single observed resolved address; this reflects answer diversity in this observation only and does not establish whether resolution is correct.
Improvement recommendations
- The DNS response rate is 1%, 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 375 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.
