Every search on DigMyName runs a stopwatch: it starts on your last keystroke and stops the moment the first availability answer hits the screen. The page explains what the timer includes, shows reference numbers measured from a single datacenter, and lets you run the same benchmark from your own connection — cold first-time lookups and cached repeats reported separately.
Nobody can prove a universal latency record. If a faster public lookup exists, it gets featured here with credit and a link back.
