UptimeRobot
Popular free uptime monitoring service checking site availability.
What is UptimeRobot?
UptimeRobot is one of the most popular website monitoring services, offering free and paid plans. Its bot periodically checks configured URLs to verify they're responding correctly, alerting site owners when downtime is detected.
The crawler makes lightweight HEAD or GET requests at configured intervals (typically every 5 minutes). It identifies itself with "UptimeRobot" or "uptimerobot" in the user-agent string and generates minimal bandwidth.
UptimeRobot traffic is always legitimate and intentional — someone has specifically configured monitoring for your site. Blocking it would prevent your monitoring from working, potentially leaving you unaware of downtime.
