Ever stumbled upon a “404 Not Found” message or seen the dreaded “500 Internal Server Error” and wondered what’s going on? These are HTTP status codes, and they’re like secret signals that servers use to communicate with browsers and let us know what’s happening when we visit a website. Some codes tell us everything’s fine while others can point to issues that need fixing. In this guide, we’ll break down the most common HTTP status codes in a simple and friendly way. Plus, we’ll show how tools like Dotcom-Monitor can help ensure your website stays error-free and your users stay happy!
What are HTTP Status Codes?
To better understand what’s happening when an error pops up, it’s helpful to know the categories of HTTP status codes. Each code starts with a number, and that number gives you an idea of what type of response you’re dealing with:
- 1xx Informational: These codes are like a “hang tight, I’m working on it” message from the server. They don’t show up much but let you know the server is still processing your request.
- 2xx Success: This is the green light from the server! It means the request was received, understood, and processed just fine. The classic “200 OK” is the one you want to see most often.
- 3xx Redirection: Think of these codes as “directions.” The server is saying, “This page has moved, follow me to the new location.”
- 4xx Client Errors: These errors mean something’s wrong on your end. Maybe there’s a typo in the URL or a page doesn’t exist anymore. A 404 Not Found is a common example of a 4xx error.
- 5xx Server Errors: Oops, something went wrong on the server’s side, even though the request was fine. A 500 Internal Server Error is a good example of this category.

Common HTTP Status Codes
- 200 OK: Everything’s working as it should! This code means the server found the page and responded successfully. It’s what you want to see most of the time.
- 301 Moved Permanently: This means a page has been permanently moved to a new location. For instance, if a URL has changed, this code sends users (and search engines) to the new address.
- 302 Found (Temporary Redirect): Unlike a 301, this redirect is temporary. It’s commonly used during promotions when sites need to direct visitors to a specific page temporarily.
- 400 Bad Request: The server couldn’t understand the request because of bad syntax, usually due to a typo or incorrect URL. It’s a gentle nudge to check and correct the request.
- 401 Unauthorized: This code means a user needs to log in or authenticate to access the page. It often appears on login pages or restricted sections of a website.
- 403 Forbidden: A 403 says the server understood the request but won’t fulfill it, typically due to a lack of permissions.
- 404 Not Found: This one’s famous. 404 means the server couldn’t find the page requested. This can happen if a URL is incorrect, or the page has been moved or deleted.
- 500 Internal Server Error: A 500 error tells you that something unexpected happened on the server. This can be due to various reasons like high traffic or code issues.
- 502 Bad Gateway: This happens when one server, acting as a gateway or proxy, receives a faulty response from an upstream server. It often indicates an issue with the main server.
- 503 Service Unavailable: This code shows the server is temporarily unable to handle the request. It might be down for maintenance or experiencing high traffic but should be back soon.
