Dear PDB-l, In 2022, wwPDB introduced DNS names <http://www.wwpdb.org/news/news?year=2022#6303be3b707ecd4f63b3d3d9> for programmatic access to PDB archive downloads: * FTP: ftp://ftp.wwpdb.org * HTTPS: https://files.wwpdb.org (replaces https://ftp.wwpdb.org) * RSYNC: rsync://rsync.wwpdb.org (replaces rsync://wwpdb.org) The PDB Archive Downloads <http://www.wwpdb.org/ftp/pdb-ftp-sites> documentation has detailed information. Starting September 2023, wwPDB will start enforcing use of these updated DNS names. URLs in which the DNS name doesn’t match the protocol (e.g., https://ftp.wwpdb.org, ftp://files.wwpdb.org) will no longer work at that time. Users who download PDB archive data programmatically are encouraged to switch to the new DNS names as soon as possible. HTTPS protocol is preferred (over FTP) for individual file downloads. Please contact info@wwpdb.org with any questions. -- Regards, Jasmine =========================================================== Jasmine Young, Ph.D. Biocuration Team Lead RCSB Protein Data Bank Research Professor Institute for Quantitative Biomedicine Rutgers, The State University of New Jersey 174 Frelinghuysen Rd Piscataway, NJ 08854-8087 Email:jasmine@rcsb.rutgers.edu Phone: (848)445-0103 ext 4920 Fax: (732)445-4320 ===========================================================
