The oVirt project has multiple mirrors that distribute the load and offer better user experience.
These are currently only used by yum/dnf on client side to detect the best mirror and use it. At the same time, while mirrors also sync ISOs we never advertise them on our website so they're always downloaded from resources.ovirt.org
CentOS for example has special software to power isoredirect.centos.org which will find the closest mirror and re-route ISO download requests.
The code is available here: https://github.com/CentOS/mirrorlists-code
This ticket is to identify if we can use something similar to direct users to the closest ISO location instead of only using the default URL.
We already do monitor our mirrors for freshness and know their geographical locations so it looks like large chunks of the logic are already in place.
