The FTP site for the new Ensembl website has a new structure. In the updated structure, files are now organised under GCA/ and GCF/ subdirectories, for example: https://ftp.ebi.ac.uk/pub/ensemblorganisms/GCA/. This structure is available for all releases on the site, including the latest partial release 2026-06-07. It will be the standard structure for all subsequent releases.
The structure organised by species name at https://ftp.ebi.ac.uk/pub/ensemblorganisms/ will be retired in August 2026. Please be aware that this change will affect workflows and pipelines pointing to this site. This structure has been maintained for partial release 2026-06-07, and it will remain for three more partial releases in July 2026. We recommend adapting pipelines or workflows to the updated structure as soon as possible.** When it is retired, data will be deleted, and URL links to these will fail.
