This DNS lookup ran on 2026-10-09 11:25 UTC. The overall DNS response rate was 93.7%, with 283 of 302 nodes returning a valid result and 19 unanswered lookups. The overseas carrier showed a notably lower response rate and is the main anomal
myfirstapi.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
- Overall DNS response rate was 93.7%, below the 99% reference threshold, with 19 of 302 nodes not obtaining a valid result.
- The overseas carrier reached a 59.4% response rate (19 of 32 nodes), about 40.6 percentage points below the mobile carrier's 100%.
- DNS lookup time was short across responding nodes, averaging roughly 2 ms overall and about 7 ms on the overseas carrier.
- Only one unique response IP was observed, so answer diversity was minimal; this describes observed answers only and does not establish resolution correctness.
Improvement recommendations
- The DNS response rate is 27.3%, 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.
