About TellMeWhenDownBot

If you're seeing requests from TellMeWhenDownBot in your logs, that's our monitoring engine checking a site someone added to TellMeWhenDown.

It identifies itself with this User-Agent:

TellMeWhenDownBot/1.0 (+https://tellmewhendown.com/bot)

The bot makes lightweight HTTP requests to check whether a site is up, inspects TLS certificates and response headers, and — only for sites whose owner has verified control — probes for common misconfigurations like a publicly exposed .env.

It never attempts to log in, submit forms, or modify anything. If you believe it's checking a site you own without your permission, contact us and we'll remove it.
