HTTP Status Checker

An HTTP status code tells you how a web server responded to a request. SiteCheckNow lets you quickly check the HTTP response returned by a website.

Common HTTP status codes

• 200 OK: The request was successful.
• 301 Moved Permanently: The website or page has been permanently redirected.
• 302 Found: The request is temporarily redirected.
• 400 Bad Request: The server could not understand the request.
• 401 Unauthorized: Authentication is required.
• 403 Forbidden: The server refuses to allow access.
• 404 Not Found: The requested page or resource could not be found.
• 429 Too Many Requests: Too many requests were sent in a given period.
• 500 Internal Server Error: The server encountered an unexpected problem.
• 502 Bad Gateway: A gateway or proxy received an invalid response.
• 503 Service Unavailable: The server is temporarily unable to handle the request.
• 504 Gateway Timeout: A gateway or proxy did not receive a timely response.

Why check an HTTP status code?

HTTP status codes can help website owners understand redirects, missing pages, access restrictions, and server-side problems. They are also useful when troubleshooting website availability and technical SEO issues.

Does a 200 status guarantee everything is working?

No. A 200 response means the server successfully responded to the request. It does not guarantee that every page, image, script, form, or feature on the website works correctly.
