THE SIGNAL

What this visit tells you

A monitor check measures availability of a configured URL. Exclude these repeated checks from customer or assistant engagement metrics.

Monitor check failures
Response time
Check cadence

Your next move

Match the cadence and endpoint to a monitor you own. A blocked check may explain a downtime alert even when browsers can load the page.

The technical details

Markdown
How to identify it

Look for the UptimeRobot identifier in a request’s User-Agent. This is a name match, not identity verification. Version strings may change.

How to check identity

Compare the source IP with UptimeRobot’s published monitoring IP list and the monitor configured for the requested URL.

Access and robots.txt

Control the monitor configuration and authenticated access; no robots.txt behavior is asserted here.

Seeing 403 or 404 responses?

403 means access was denied; 404 means the resource was not found. Compare the public path, request time, edge security event and origin response to find the cause.

Separate intended restrictions and secret-file probes from pages that should work. A User-Agent name alone does not justify allowing a request.
