OpenBSD Mirrors


OpenBSD can be obtained via HTTP(s) or FTP. Typically you only need a single small piece of boot media and then the rest of the files can be installed from a number of locations, including directly off the internet. Consult the installation guide for details.

Choose a mirror near you from the following list of HTTP(s), FTP and rsync mirrors which provide OpenBSD.

See below for the directory layout of mirrors and information for prospective mirrors.

Information for Prospective Mirrors

To be listed on this page we require mirrors to be fast, up to date, capable, and well-connected to networks in the region in which they serve.

Mirrors must carry the following:

Also:

As of March 2020, the minimum space required is approximately 750GB. However, to reduce problems for users when snapshot packages are updated, it is strongly recommended to use the rsync options --delete-delay --delay-updates which require additional space during updates. --fuzzy may also be helpful to reduce the amount of data transferred when updating snapshot packages. Depending on the disk space available, mirrors may provide more contents, such as older releases, current source tree, etc.

A suggested httpd.conf(5) configuration for httpd(8) that is suitable for being www and ftp space mirror is here.

Operators of mirrors who are interested in having their site added to the list on this page should contact mirrors-discuss@openbsd.org with further details about their site, including network connectivity, geographic location, and general information. We will suggest a suitable second-level mirror to sync from; do not mirror from ftp.openbsd.org.

Mirror operators should subscribe to the low-volume mirrors-announce mailing list.
