HTTP Status Check

What is HTTP?

HTTP (HyperText Transfer Protocol) is the foundation of data communication on the web. Every time a browser loads a page, it sends an HTTP request to a server, and the server replies with a response that includes a status code — a three-digit number indicating whether the request succeeded, failed, or needs further action.

HTTP was originally defined in RFC 1945 (HTTP/1.0) and evolved through RFC 9110 (HTTP Semantics, the current standard).

What is an HTTP Status Check?

An HTTP status check sends a request to your website and evaluates the response code returned by the server. A successful response (2xx) means the site is up; codes like 4xx or 5xx indicate problems.

Common Status Codes

  • 200 OK — The page loaded successfully.

  • 301/302 — Redirect. DigiPulse follows redirects automatically.

  • 404 Not Found — The page does not exist.

  • 500 Internal Server Error — The server encountered an error.

  • 503 Service Unavailable — The server is temporarily down or overloaded.

Why It Matters

This is the most fundamental check. It detects outages instantly and is the fastest check available. Use it as the baseline for every site you monitor.
