A 404 error is a status code that is shown when a requested URI on a server does not exist or could not be found. An example of a 404 error on Scratch can be viewed here.
On Scratch
404 errors are displayed when one searches for a nonexistent user, or when one searches for a nonexistent or removed project. If one searches for a user that once existed but their account has been deleted, it will return a 404 error to everybody except for the Scratch Team. If a project has been flagged by the logged in user, visiting that project will return a 404 error on the account they reported it with as well. Attempting to visit unshared projects now also returns a 404 error, although this previously had a dedicated page.
The text, "Whoops! Our server is Scratch'ing its head" is displayed, along with a picture of a puzzled Giga with a magnifying glass.
Image
The Scratch 404 page did not always have an image on it. In December, 2009, the then-Scratch Team member andresmh asked for an image to adorn the 404 page.[1] The chosen image was made by the Scratcher DavidTy.[2] He was credited with the creation beneath the image on the page. In Scratch 2.0 this image was replaced with a grey image of the Scratch Cat, then on December 1, 2014, the image was replaced with Giga with a magnifying glass.
