This website is not using a custom 404 error page! Default 404 error pages result in a poor experience - it can mislead users into thinking an entire site is down or broken, greatly increases the chance they leave the website entirely, and looks unprofessional. We recommend to have a custom 404 error page in order to improve the website's user experience by letting users know that only a specific page is missing/broken (and not the entire site), providing them helpful links, the opportunity to report bugs, and potentially track the source of broken links.
