Web archives and sites with DMCA
<p>Assume the following:</p>
<ul>
<li>A website is indexed by a web archive like <a href="https://web.archive.org/" rel="nofollow noreferrer">the wayback machine</a>.</li>
<li>The website receives a DMCA takedown and the content is removed.</li>
</ul>
<p>Does the web archive need to remove the saved content as well or only if the web archive receives a DMCA takedown, too?</p>
<p>Are there mechanisms in place to automatically remove content if the archiver detects a <code>451 unavailable for legal reasons</code> HTTP status code?</p>

<p>Nothing in <a href="https://www.copyright.gov/title17/92chap5.html#512" rel="noreferrer">17 USC 512</a>, which includes the DMCA Safe Harbor and Takedown procedures requires an online service provider to notify others who may have made copies of content (including archive sites) claimed to be infringing that a takedown notice has been received or that access to the content has been blocked or removed.</p>
<p>A separate DMCA takedown could be sent to the archive site.</p>
<p>The internet archive honors robots.txt files set to deny access to a particular  site, page, or section of a site by removing from public view all archived versions of that content. This is often done when a new owner acquires a domain and it is repurposed or put up for sale. To the best of my understanding there is no legal requirement that an archive act in this way, but the IA at least does so.</p>
