Comment 18 for bug 1984175

the change at https://review.opendev.org/c/opendev/system-config/+/852793 merged so I think that is actually what fixed us in this case.

The times seem to match up looking at the green runs in build history (attaching screenshot here).

[EDIT]: perhaps both things... per https://lists.centos.org/pipermail/centos-devel/2022-August/120525.html root cause of facebook mirror issue was fixed. and we also switched to rax mirror which seemed to be fine throughout.
