IU13 provides public high-speed mirroring of several open source projects that are used by IU13 and WAN members.

mirrors.iu13.net currently hosts:

If you would like to request a local mirror of another project, please contact the WAN team.


To configure Ubuntu systems to update from mirrors.iu13.net, execute this script (tested on Ubuntu 18, 20, and 22):

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak ; echo "$(cat /etc/apt/sources.list.bak | sed -n 's/http.*archive.ubuntu.com/https\:\/\/mirrors.iu13.net/p' | cat - /etc/apt/sources.list.bak)" | awk '!seen[$0]++' | sudo tee /etc/apt/sources.list

If you need to undo the changes, execute this command:

sudo cp /etc/apt/sources.list.bak /etc/apt/sources.list
