Understanding HTTP Status Codes: A Guide for Webmasters

Every time you request a webpage, the server responds with a status code. 200 is the goal—it means everything worked as expected. But what about the others? 404 is the classic "Not Found," while 403 indicates a "Forbidden" access issue, often caused by firewall misconfigurations.

The 5xx series of codes are the most critical for monitoring. A 500 Internal Server Error often points to a code bug, while a 503 Service Unavailable usually means the server is overloaded or down for maintenance. Knowing the difference is key to fast troubleshooting.

Our system doesn't just see "Down"—it logs the specific HTTP code and even captures the error message from the body. This level of detail saves your developers hours of digging through server logs during an incident.
