updown.io daemon is a website monitoring bot that performs uptime and performance checks on websites and online services. It visits websites at scheduled intervals to verify availability, response times, SSL certificate validity, and other metrics as configured by the monitoring service customers.

At a glance

Operator: updown.io
Type: Other

How Centinel checks it

User agent: The request calls itself this crawler. Anyone can send the same string.
IP ranges: The operator publishes the addresses it crawls from, and Centinel checks the client address against that list.

A request that passes one of these checks is updown.io daemon itself. One that only matches the user agent is reported as unverified. The match tokens, verification domains, and address feeds are not published here.

Allowing or blocking it

The crawler object in the /validate response sets access_allowed to true only for a verified source that your tenant allowlists. A policy rule can allow or block this crawler by its category, Other.
