See whether a website responds
A status check requests the homepage of a public domain and reports the HTTP response. Codes in the 200 range indicate a successful response. Codes in the 300 range indicate a redirect, while 400 and 500 range responses show that the server answered but could not serve the request as expected.
Understand the limits of one check
A website may answer from one location and fail from another. A firewall may also reject automated requests even when a normal browser works. This tool uses a HEAD request, checks the domain's IPv4 address, and does not follow a redirect. A failed result is a starting point for troubleshooting, not proof of a worldwide outage.
What to investigate next
If DNS does not resolve, inspect the A record and name server settings. If the HTTP response is a redirect, open the site in your browser and check its destination. If HTTPS fails while HTTP responds, review the certificate and server configuration. For continuous monitoring, use a dedicated service that checks from multiple locations over time.
