# CentOS Mirror managements SOP
`mirrors.centos.org` is an alias to mirrors.fedoraproject.org and so is a MirrorManager instance hosted by Fedora infra team. Let's see which process to follow when we get a ticket (see [Howto on the wiki](https://wiki.centos.org/HowTos/CreatePublicMirrors) ) to add/remove/modify a mirror entry in corresponding DB.
## CentOS Stream 9 and beyond
When we get a new request for CentOS Stream mirror, the process goes like this :
* ticket is reviewed by infra-and-releng team and tagged with `mirrormanager` label
* assignee should :
* verify that mirror isn't located at GeoIP level from an [embargoed country](https://www.centos.org/legal)
* verify that provided URLs (http/https and - optional - rsync) are working
* follow the link to that mirror in mirrormanager (needs `sysadmin-web` FAS group membership)
* add the `CentOS` category and then add the URLs
* On `mon.rdu2.centos.org`, update the file `/var/lib/centos-infra/stream-mirror.list` with the IPs to be add in ACL (one IP per line)
* update ticket with info and close
