IU13 provides public high-speed mirroring of several open source projects that are used by IU13 and WAN members.
mirrors.iu13.net is an official mirror of:
CentOS (up to version 8)
CentOS Stream (version 9 or higher)
If you would like to request a local mirror of another project, please contact the WAN team.
How do I use the mirror?
To configure Ubuntu systems to update from mirrors.iu13.net, you need to add mirrors.iu13.net to your apt sources list.
The script provided below (tested on Ubuntu 18, 20, and 22) automatically backs up your current apt sources list and adds entries for mirrors.iu13.net. It does not remove your current sources.
If you need to undo the changes, execute this command:
Enterprise Linux (Rocky, CentOS, EPEL)
These operating systems use yum or dnf to query a MirrorManager server that automatically directs you to a nearby mirror, so typically no manual configuration is required.
