This DNS lookup for cook-yee.vercel.app ran at 2026-09-30T04:05:55.789Z. All 12 nodes returned no valid DNS response, giving a 0% DNS response rate and no observed resolved address. This is a time-bound observation only.
cook-yee.vercel.app 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
- All 12 nodes produced no valid DNS response; respondedNodeCount is 0 and the DNS response rate is 0%, below the 99% threshold.
- No DNS lookup time was recorded on any node, so p50, p90, p95 and average values are empty and resolver timing cannot be compared across carriers.
- Telecom had 7 nodes, Unicom 2 and overseas 3, all unanswered; mobile had 0 nodes, and unique response IP count was 0, showing no observed answer diversity.
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.
