404 error
The web response you get when the page or resource you asked for cannot be found
What's it for?
Tells someone that the page or item they asked for cannot be found.
For example…
Clicking an old bookmark to a deleted policy page shows a 404 instead of the document
A mistyped product URL returns a 404 because no page exists at that address
Think of it like…
A postcode that no longer exists on the map — the address format is fine, but nothing is there anymore
