# What is the "Is [site] down?" tool?

> The is-down tool checks any public URL from an outside vantage point and tells you if the problem is you or the site itself.

## Quick answer

 The is-down tool is a free public probe. Paste any URL and Lemwatch fetches it from an outside server, returning HTTP status, response time, and DNS resolution.

## What it checks

- HTTP status code and redirect chain

- DNS resolution (A / AAAA / CNAME)

- TLS handshake and SSL validity

- Response time from a single region

## Where to find it in Lemwatch

 **/is-down** or **/is-down/<domain>** — no login required.

## When to use it

- A visitor reports "site down" but it works for you

- You want a fast neutral opinion before opening a ticket

- You need a shareable link proving the outage

## FAQ

### Does the tool retry?

 Single probe by default. Refresh for a fresh check.

### Can I monitor continuously?

 Yes — sign up and add the site for scheduled uptime checks.
