DNS name changes for PDB archive downloads from RCSB PDB starting September 2023
In 2022, RCSB PDB introduced DNS names for programmatic access to PDB archive downloads:
- FTP: ftp://ftp.rcsb.org
- HTTPS: https://files.rcsb.org (replaces https://ftp.rcsb.org)
- RSYNC: rsync://rsync.rcsb.org (replaces rsync://rcsb.org)
The File Download Services documentation has detailed information.
Starting September 2023, RCSB PDB will start enforcing use of these updated DNS names. URLs in which the DNS name doesn’t match the protocol (e.g., https://ftp.rcsb.org, ftp://files.rcsb.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.
