New error message file
The current 404 error page served by Wikimedia is ugly and has a few problems:
- It has a meta refresh on the client-side, which is pretty much universally discouraged for accessibility purposes;
- The 'foundation' in the footer is not capitalised;
- It doesn't give the right 404 header, instead serving a "200 OK" code, which is apparently problematic.
It is also subject to a pretty scathing critique at the following URL:
I've whipped up a new page which I think looks better and does the job better (see attachment). It uses 3 images on Commons.
If you choose to implement this replacement, you would need to make sure to spit out the 404 URL in the page title and in the italics paragraph, and a modified version of this in the "check" link to whack a "/wiki/" before it (presumably the same code that is presently used in the meta http-refresh code). You would also need to fully protect File:Errorline.png and File:Errorbg.png on Commons.
