<div>{{HTTPSidebar}}</div>
<p>The HTTP <code><strong>404 Not Found</strong></code> client error response code indicates that the server can't find the requested resource. Links which lead to a 404 page are often called broken or dead links, and can be subject to <a href="https://en.wikipedia.org/wiki/Link_rot">link rot</a>.</p>
<p>A 404 status code does not indicate whether the resource is temporarily or permanently missing. But if a resource is permanently removed, a {{HTTPStatus("410")}} (Gone) should be used instead of a 404 status.</p>
<h2 id="Status">Status</h2>
<pre class="syntaxbox notranslate">404 Not Found</pre>
<h2 id="Custom_error_pages">Custom error pages</h2>
<p>Many web sites customize the look of a 404 page to be more helpful to the user and provide guidance on what to do next. Apache servers can be configured using an <code>.htaccess</code> file and a code snippet like the following example.</p>
<pre class="brush: bash notranslate">ErrorDocument 404 /notfound.html</pre>
<p>For an example of a custom 404 page, see <a href="https://developer.mozilla.org/en-US/404">MDN's 404 page</a>.</p>
<div class="note">
<p>Custom design is a good thing, in moderation. Feel free to make your 404 page humorous and human, but don't confuse your users.</p>
