September 19: DNS name changes for PDB archive downloads from RCSB PDB
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 19, 2023, RCSB PDB will start enforcing use of these updated DNS names (previous announcement). 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. HTTPS protocol is preferred (over FTP) for individual file downloads.
