FAQs – Website Status Checker

1. What does this Website Status Checker do?

It tests any website in real time to see if it is online (UP) or offline (DOWN). The tool checks server availability, response time, and HTTP status codes.

2. How do I check if a website is down?

Simply type the domain name (e.g., example.com) into the search box and the tool will automatically test the website and show the results instantly.

3. Do I need to enter “https://” before the domain?

No. You can enter just domain.com and the tool will automatically add the correct protocol.

4. Why does a website show as DOWN for me?

If a site appears down, it may be due to server outages, maintenance, DNS issues, or network errors. The tool checks from external servers, so it helps determine whether the issue is global or only local to your device.

5. What does the HTTP status code mean?

The status code tells you how the website responded:

  • 200 – The website is working normally
  • 301/302 – Redirect
  • 404 – Page not found
  • 500+ – Server-side error
  • 503 – Service unavailable
6. What is response time?

Response time is the speed (in milliseconds) it takes for the website’s server to answer the request. A lower number means faster website performance.

7. Can this tool detect server-side issues?

Yes. It can detect common server-side errors such as downtime, slow response, misconfigurations, or unreachable servers through status codes and response data.

8. Is the Website Status Checker free to use?

Yes, the tool is completely free and requires no registration.

9. How often can I check a website?

You can check as many websites as you want, as often as you like. There are no limits.

10. Can I monitor multiple websites?

You can manually check any number of websites. If you need continuous monitoring, we can help you integrate additional uptime tracking tools.

11. Why does the site show UP here but DOWN for me?

This could mean there’s an issue with:

  • Your internet connection
  • Browser cache
  • Local DNS
  • Firewall or network restrictions

The website itself may still be working globally.

12. Does this tool store any of the websites I check?

No. The tool simply checks the provided URL and does not store or log any personal data entered by users.
