Per discussion on this list some time ago (https://lists.centos.org/hyperkitty/list/devel@lists.centos.org/thread/BYSKA...) , and also aligned with CentOS Stream 8 EOL (including for SIGs content), we'll proceed next Monday with the announced change :
The SIG that opted in to build against/for RHEL8 (and not CentOS Stream 8) had their packages pushed the same way centos linux 7 was. Per thread linked above, there was a proposal from the kmods SIG (and no other SIG minded against) to start pushing to the mirror.stream.centos.org network (instead of "legacy" mirror.centos.org, which will be empty soon), and so starting to be using mirrormanager (as mirrorlists.centos.org service itself will disappear end of June, due centos linux 7 going EOL)
Since March 2024, there was a script that was just keeping http://mirror.centos.org/centos/8/<SIG>/ content in sync with the new destination https://mirror.stream.centos.org/SIGs/8/<SIG>/ . That ensured that SIGs would have enough time to communicate the new location and also provide eventually newer .repo files
# What will happen next week ? Content from mirror.centos.org will be emptied (for both 8-stream and 8) and SIG content for 8 (rhel8) will be pushed to new location directly (no intermediate step)
# What about your .repo files ? Same rule as for 9-stream and so documented in the SIG guide : https://sigs.centos.org/guide/delivery/#centos-stream-9-and-above_1
Kind Regards,
