Dear PDB-l, 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. 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. wwPDB has traditionally supported FTP, together with HTTP/S and RSYNC. Gradual deprecation of the FTP protocol, in favor of the HTTP/HTTPS protocol will be approached while maintaining support for the RSYNC protocol which offers additional functionality compared to the other 2 protocols. As announced previously <http://www.wwpdb.org/news/news?year=2022#6303be3b707ecd4f63b3d3d9>, we have introduced DNS names that are specific to the protocols: * files.wwpdb.org for HTTP/S * ftp.wwpdb.org for FTP. To be deprecated on November 1st 2024. Note that from September 2023 this DNS name will not accept HTTP/S traffic. * rsync.wwpdb.org for RSYNC Starting September 2023, wwPDB will start enforcing use of these updated DNS names for the preparation of FTP protocol deprecation.
