Here’s The Interesting Reason Why Error 404 Is Called Error 404


Last Updated on 2023-06-27 , 12:12 pm

Ever attempted to explore a corner of the internet, only to be faced with a sternly presented 404 error message?

You’re certainly not the only one. There’s something uniquely frustrating, yet intriguing about the 404 error code.

In this article, we delve into the ins and outs of the 404 error code, explain why 404 is used for error, and bust some myths about why it’s called 404 error.

Delving into the 404 Error

The notorious “404 error” code essentially means that the webpage you’re keenly trying to access has seemingly vanished off the server’s radar.

It’s a ‘client-side’ error, which technically implies that the misstep occurred on your end.

So, the next time you’re confronted with a 404 error, it might be time for a self-check.


A Deep Dive Into the Intricacies of the 404 Error Code

Error 404 is fundamentally a HTTP status code.

You see, each time you enthusiastically try to gain access to a webpage, your computer reaches out to the server with a handshake using HTTP, or Hypertext Transfer Protocol.

For a regularly functioning webpage, the status is cheerily set at 200 OK, a status you would never observe because the content is already beaming on your screen.

However, when an error pops up, you get to witness the real deal – the error code like 404 Not Found.


But What Does the 404 Error Code Actually Mean?

The error 404 code carries with it a hidden language. The first ‘4’ is a subtle hint that you might have fumbled, possibly misspelling the URL or pining for a page that has mysteriously disappeared.

The middle ‘0’ is a red flag for a general syntax error, meaning the URL is a bit off-kilter. The final ‘4’ of the triad signifies the specific error nestled in the 40x group.

Why 404? The Legend Behind the 404 Error Code

Why is it called 404 error? There was an old legend that floated around stating that the “error 404” was christened after a room at CERN (European Organization for Nuclear Research), home to the original web servers.

Alas, this myth was debunked by none other than Tom S., who reported a disappointing lack of Room 404 during his visit to CERN.

Tom went on to explain that in CERN’s office numbering system, the initial digit ‘4’ denotes the building number, while the final two digits allude to the office number.

So, there’s a hard truth we need to face – there’s no mythical Room 404 at CERN, nor is it preserved as a relic of the dawn of the internet. The famed “Room 404” is simply a web fable.

Here’s my theory

Here’s a whimsical theory to ponder upon. Could the 404 error have found its name inspired by the elusive Room 404 in CERN, because, like the error, it simply can’t be found in our tangible world?

Perhaps someone in the annals of internet history might have thought – hey, we can’t find Room 404 here. Why not use it as a code for something that’s similarly elusive?

So, dear reader, what do you think about this wild theory? Does it sound plausible or is it just another cyber-urban legend?

No matter what the true origins of the 404 error code are, there’s no denying that it’s a fascinating piece of internet lore.


So what do you think? Sounds legit?
