ua-tracer
what does a user agent actually fetch, follow & run?
All recent homepage requests, newest first. This page does not mint a new trace (unlike /), so you can browse the log without adding noise.

on its own initiative.

user agent and IP within 30 minutes (the same crawler that fetched a well-known file usually also
loaded /). The offset shows how long before/after the probe that trace was minted.
