RPMFusion el8 buildroot broken?

I am getting an error from koji when trying to build for el8: BuildrootError: could not init mock buildroot, mock exited with status 30; see root.log for more information The mock_output.log shows: Error: Error downloading packages: Status code: 404 for http://mirror.centos.org/centos/8/BaseOS/x86_64/os/Packages/bash-4.4.20-2... (IP: 192.168.182.1) Relevant task example: https://koji.rpmfusion.org/koji/taskinfo?taskID=522207 I am presuming that this is an infrastructure issue somewhere, and all I can do is wait for the project system admins to resolve this issue. If there is something I can do, please let me know.
