| Benchmarks neutral DNS providers by measuring TCP port 53 latency (RTT in ms) to determine the fastest DNS server. | ||

| Array of PSCustomObjects containing Provider, PrimaryIP, and LatencyMs sorted by lowest latency. | ||

Fresh evidence in this update is that the new exclusion condition only skips AGENTS.md reference: AGENTS.md:L86-L86 Useful? React with 👍 / 👎. |
