Tiering
Fedora mirror servers use Tiering, whereby a select few fast mirrors get read access to the master rsync servers, and all the other mirrors pull from those mirrors.
For our purposes, define:
- master: The Fedora-owned servers dl.fedoraproject.org
- Tier 1: The fast mirrors which pull from a master mirror.
- Tier 2: The mirrors that pull from the Tier 1 servers.
Properties of Tier 1 mirrors:
- Limit the number of Tier 1 mirrors, to ensure adequate bandwidth for these. Adjust number up or down depending on capability of the masters.
- Must carry everything under fedora-enchilada and fedora-epel. This allows Tier 2 mirrors to exclude what they wish, but get everything if they so wish. This means at least 1TB of disk space for the Fedora portion of this server.
- Must have a 1 Gigabit connection to the Internet, or faster.
- Must have an active, available, responsive mirror administrator during the days content is staged.
- Must have at least 2 Internet2-connected Tier 1 mirrors.
- Must have at least 1 Tier 1 mirror on each continent for which we have Tier 2 mirrors.
- Must serve private rsync (see below for configuration).
Master mirrors
- dl0[123].fedoraproject.org, in Phoenix, AZ, USA.
- dl0[45].fedoraproject.org, in Phoenix, AZ, USA - tier1 mirrors only.
- dl.fedoraproject.org is a DNS round-robin to dl0[123].
- dl-tier1.fedoraproject.org is a DNS round-robin for dl0[45].
Master mirror rsync modules
The master mirrors provide two additional rsync modules which provide pre-bitflip content. Fedora tiered mirrors should use these modules to be able to get pre-bitflip content.
Module name | Content |
---|---|
fedora-buffet0 | Everything under /pub/, including pre-bitflip content |
fedora-enchilada0 | Everything under /pub/fedora/, including pre-bitflip content |
fedora-epel0 | Everything under /pub/epel/, including pre-bitflip content (even though EPEL doesn't do bitflips) |
Tier 1 mirrors
Tier 1 mirrors pull from one of the master mirrors.

Tier 1 rsync configuration
Below is an example rsyncd.conf file for a Tier 1 mirror that provides private rsync access to select downstream Tier 2 mirrors. You may do this via either IP or DNS-based access control, or by a shared username/password which you give to your selected Tier 2 mirrors directly.
The key to this is that the Tier 1 mirror rsyncs content using a user account (e.g. mirror used below), and you serve content to Tier 2 mirrors using a private rsync module that runs as that same user account, while providing public non-authenticated rsync using the nobody account. In this way, Tier 2 mirrors may obtain content before the permissions are made world readable.
