    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#

  1. HTTP status code and redirect chain
  2. DNS resolution (A / AAAA / CNAME)
  3. TLS handshake and SSL validity
  4. Response time from a single region
  5. Where to find it in Lemwatch#

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

    When to use it#

  6. A visitor reports "site down" but it works for you
  7. You want a fast neutral opinion before opening a ticket
  8. You need a shareable link proving the outage
  9. 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.
