<p>The FTP protocol for file downloads has been losing popularity over the years in favor of HTTP/S. There are many advantages of HTTP/S including speed, statelessness, security (HTTPS), and better support. Importantly during the past 2-3 years the main web browsers (Chrome and Firefox) have dropped support for the FTP protocol, which has effectively discontinued the FTP protocol for non-technical users.</p>
<p>Given that the majority of file download activity on the internet has moved to HTTP/S, wwPDB plans to deprecate FTP download protocol on November 1st 2024 (<a href="https://urldefense.com/v3/__http://www.wwpdb.org/news/news?year=2022*636151b266d6046810db7f0f__;Iw!!Mih3wA!Ha94EnbU1FkoZkzZoOVAmfyg_LimxB01-RQq8clFi9sSblQAOsCrloOOiWE8aQOShaSh-6raqDTdvLYDNaMsNivI$" target="_blank" rel="noopener noreferrer">see previous announcement)</a>.</p>
<p>Support for the RSYNC protocol, which offers additional functionality, will continue to be maintained.</p>
