About Server Status Checker

Use the Server Status Checker to inspect the HTTP response observed for a public URL. It can help distinguish a successful response from a redirect, access restriction, missing page, rate limit, or server error. The result describes one request at one moment; it does not establish continuous availability or explain the underlying cause by itself.

Check the exact URL involved

  1. Enter the full public address, including the correct protocol, subdomain, path, and any necessary public query string.
  2. Run the check and record the returned status code.
  3. Compare the result with the page in your browser and, if possible, another known page on the same site.
  4. If the result is unexpected, check again after a reasonable interval and review server logs, hosting information, or recent configuration changes.

Test the affected page rather than relying only on the homepage. A homepage may return 200 while an article, product page, API route, or other resource returns an error.

Avoid submitting password-reset links, session URLs, access tokens, private preview addresses, or confidential query parameters. Inspect everything after the question mark in a URL before using it.

How to interpret common responses

Code What it usually indicates Useful next check
200 The server accepted the request and returned a successful HTTP response. Open the page and verify that the expected content appears. A custom error page or incomplete response can still use a 200 code.
301 The resource has a permanent redirect. Confirm that the destination is intentional, relevant, and reachable.
302 The resource has a temporary redirect. Check whether the temporary behavior is expected and whether the destination changes under different conditions.
403 The server understood the request but refused access. Review permissions, firewall rules, bot controls, authentication requirements, and regional restrictions.
404 The requested path was not found. Check the spelling and path, then determine whether the page was removed, moved, or never published at that address.
429 The server is limiting requests. Stop repeated checks, wait, and review rate-limit or traffic-control settings if you manage the site.
5xx The server or an upstream service encountered an error. Review application logs, hosting health, recent deployments, proxy configuration, and dependent services.

Common 5xx responses include 500 for a general server error, 502 for an invalid upstream response, 503 for temporary unavailability, and 504 for an upstream timeout. These labels narrow the investigation, but they do not identify the exact failing component.

Worked example: checking a moved article

Suppose an old article was located at https://example.com/guides/old-page and has been replaced by https://example.com/guides/new-page.

  1. Check the old address. It returns 301.
  2. Inspect the redirect destination. If it points to the new article, the first response matches the planned permanent move.
  3. Check the destination separately. A 200 response suggests that the new URL is reachable, but the page should still be opened to confirm that it contains the intended article.
  4. If the destination returns 404 or 5xx, the redirect exists but sends visitors to a broken or unavailable resource.

For a closer look at the route between addresses, use the WWW Redirect Checker. Redirect status alone does not show that the destination is useful or that every redirect hop is intentional.

Do not treat one request as a final diagnosis

A common mistake is to read a single failed check as proof that the entire server is down. A 403 may reflect an access rule applied to the checker rather than ordinary visitors. A 429 may follow repeated requests. A 404 can be limited to one incorrect path while the rest of the site remains available.

The reverse mistake also matters: 200 does not prove that the page works correctly. The returned document might contain an error message, missing content, or references to resources that fail later. You can inspect the response further with the webpage source code tool, then compare it with what appears in a normal browser.

Limits and sensible follow-up

A specific limitation is that the check may come from a different network location and use different request headers from your browser. DNS routing, content delivery networks, firewalls, cookies, authentication, caching, and geographic rules can therefore produce different responses for different visitors.

If a problem persists, record the complete URL, status code, approximate time, affected pages, and any recent site changes. Compare the specific page with the homepage, test from another authorized connection, and consult server or application logs when available.
