Due to internal scheduled maintenance on the CentOS Stream build infra, it will not be available/reachable this Friday August 30th (maintenance starting around 12:00am UTC)
While it will not have any impact on CentOS Stream users (not using any service hosted in that infra), it can potentially impact some SIGs, depending on their koji/cbs tag(s) configuration.
Normally SIGs are just using released repositories (aka what's available through mirror.stream.centos.org) but some SIGs requested to inherit CentOS Stream (9 and 10) buildroots repositories (to access some unreleased -devel pkgs or else)
If you're relying on these buildroots, they'll be unavailable for some hours so you should plan accordingly and eventually just queue your pkgs build for after the maintenance window, or just retry failing builds due to some pkgs from the corresponding buildroots repositories not being reachable.
Kind Regards,
