Website Down Checker

Enter any URL or domain to instantly check if the site is online, offline, or responding with errors - and see live DNS records.

e.g. google.com · github.com · https://example.com

Privacy First: Your files are processed securely. Whenever possible, processing happens in your browser and files are never stored on our servers.

Enter any URL or domain name to check whether a website is currently online or offline. The tool makes a live HTTP request via a global proxy and returns the exact HTTP status code (200, 301, 403, 503, etc.) with a plain-English explanation, the server response time in milliseconds with a Fast/Moderate/Slow rating, the Content-Type and page size from response headers, and the final URL after any redirects. A color-coded status banner instantly tells you if the site is Online (green), Responding with Errors (yellow for 4xx), or Offline/Unreachable (red for 5xx or no response). DNS Records are fetched in parallel from Google's DNS over HTTPS API - A records (IPv4 addresses), AAAA records (IPv6), MX records (mail servers with priority), NS records (name servers), and TXT records (SPF, DMARC, domain verification tokens) - all with their TTL values. A session history panel tracks your last six checks with one-click re-check. Every field can be copied to clipboard with one click. No login, no account, and no data stored - every check is performed live in real time.

How to Use

  1. 1Type or paste any URL or domain into the input box - you can include https://, www., a full URL, or just a bare domain like github.com
  2. 2Click 'Check' or press Enter - the tool pings the server and fetches DNS records simultaneously (typically takes 2–6 seconds)
  3. 3Read the status banner at the top: green 'Online' means the site is up, yellow 'Responding with Errors' means the server replies but with a 4xx error, and red 'Offline' means the site is unreachable
  4. 4Check the HTTP Status card - it shows the exact status code (e.g. 200, 404, 503) with a plain-English label
  5. 5Check the Response Time card - Fast (under 500ms), Moderate (500–1500ms), or Slow (over 1500ms) tells you how quickly the server is responding
  6. 6Check the URL Details section - if the site redirected you, both the original URL and the final destination URL are shown with a 'Redirected' badge
  7. 7Click 'DNS Records' to expand the section - see A (IPv4), AAAA (IPv6), MX (mail servers), NS (name servers), and TXT records with TTL values
  8. 8Use the copy icon next to any field to copy IP addresses, hostnames, or TXT record values to your clipboard
  9. 9Scroll down to see 'Recent Checks' - your last 6 checks are listed with status, response time, and a Re-check button
  10. 10Click 'Re-check' on any history entry to re-run that check and get fresh results instantly
