Hello! This page loads a bunch of images from random server names within the domain and displays how long the DNS lookup took, as compared to the time spent between the sending of the HTTP request and the start of the response.

This is a crude metric of how fast your nameserver is. Note that the domain is single-hosted in Amsterdam right now, so this page is also a metric how far away you are from Amsterdam.

Note, if you are using a proxy or socks, DNS lookup times will be reported as zero.

For DNSSEC statistics, try https://metrics.lua.powerdns.org.

Note: this page logs DNS performance statistics
