We at Dr. Link Check see lots of server error pages in our daily work, and honestly, the majority of them are downright boring. You can find a great “404 Not Found” page here and there, but other common errors (such as “403 Forbidden” or “503 Service Unavailable”) rarely get much love from web developers and designers.
That’s why we decided to ask a designer to come up with ideas for turning HTTP error codes into creative artwork. The result is a set of nine images that we make available free of charge under the Creative Commons CC BY 4.0 license.
The images are in SVG vector and PNG raster formats. Feel free to use them as is, modify them to your taste, or see them as inspiration for your own creations.
