The best way to get an OpenBSD release (-release) and support us is to buy a 3 CD set. More information is available on our ordering page.
If you choose not to buy an OpenBSD CD-ROM, you can also install OpenBSD with a CD-ROM or flash disk you create yourself. To achieve this, you have to download one of the following ISO or file system image files from our mirrors:
If you choose cdXX.iso or minirootXX.fs, you will need to get the base and X sets via another media or network. Otherwise, if you choose installXX.iso or installXX.fs, you will not need anything but the application packages.
Note that the paragraph above is also valid for the people interested in running -current. You can fetch installXX.iso from the latest snapshot and install or upgrade your system very quickly.
Choose a mirror near you from the following list of HTTP, FTP and RSYNC mirrors which provide OpenBSD.

The file structure of each server is roughly:
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. Our policy requires mirrors to carry at least the last two releases in binary form (currently 6.0 and 5.9), snapshots, as well as the other associated directories (including OpenSSH/, OpenNTPD/, OpenBGPD/, patches/ and tools/), and keep them current; snapshots should not be older than a week. Use the rsync options "--delete-delay", "--delay-updates" and "--fuzzy" when updating your mirror. Note that in the above, "release" means all files under the specific directory. This includes all architecture subdirectories and the complete packages subdirectory, with packages for all application architectures. As of 6.0, the minimum space required is approximately 500GB. 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.
