FloPulse is the uptime monitor Farlo uses for the websites it manages. It requests each monitored page every few minutes from Cloudflare's network, identifying itself with the user agent FloPulse/1.0 (+https://status.farlo.io/about).
If you run one of these sites behind a firewall or bot protection and need to let FloPulse through: on Cloudflare, add a WAF skip rule for cf.worker.upstream_zone eq "farlo.io"; elsewhere, ask Farlo for a per-site token header to allow.
