The Wikimedia Foundation hosts the following public mirrors via http:

This service carries the dual purpose of giving back to the FOSS projects we use and as our own mirror.

Upstream links

These are the Debian and Ubuntu mirror pages listing to confirm it as official:

Technical info

As of December 2021 they are hosted on

The server is located at the Equinix data center in Ashburn, Virginia, United States (eqiad).

The relevant Puppet class is modules/role/manifests/mirrors.pp.

The repo for the puppet code can be git cloned with "git clone" from Wikimedia's Gerrit installation.

Monitoring and debugging

There are 2 Icinga checks called "Ubuntu mirror in sync with upstream" and "Debian mirror in sync with upstream" respectively.

If one of these alerts you should check on mirror1001 what happens if you manually run the check commands, "/usr/local/lib/nagios/plugins/check_apt_mirror /srv/mirrors/ubuntu" / "/usr/local/lib/nagios/plugins/check_apt_mirror /srv/mirrors/debian".

Also you can run the actual sync command manually but make sure to run it was the user "mirror", so "$ sudo -u mirror ftpsync".

Furthermore, you can check /etc/ftpsync/ftpsync.conf to see which upstream hosts we are rsyncing from and look at /var/log/ftpsync/ to check logfiles for errors.

For Debian you can also see if you are receiving SSH triggers: tail -F /var/log/auth.log | grep forced-command

Contacting Wikimedia maintainers

The mirror server is maintained by the Wikimedia SRE team. To report issues with, please create a ticket in Wikimedia's Phabricator and tag it with 'SRE'. You can also join the Libera.Chat IRC channels #wikimedia-operations connect and #wikimedia-tech connect.

Contacting upstream maintainers

  1. Debian
    • Email:
    • IRC: irc://
    • Method: SSH Trigger, syncs are triggered by an SSH forced key command for the mirror user. Debian has StrictHostKeyChecking no set on their side, so changing our SSH host key does not affect Debian's trigger.
  2. Ubuntu
  3. Debian OpenStack Backports
  4. Tails
