This seems like a similar issue we had recently: https://pagure.io/fedora-infrastructure/issue/11640

Working-around by:
Host vmhost-x86-copr01.rdu-cc.fedoraproject.org vmhost-x86-copr02.rdu-cc.fedoraproject.org vmhost-x86-copr03.rdu-cc.fedoraproject.org vmhost-x86-copr04.rdu-cc.fedoraproject.org vmhost-p08-copr01.rdu-cc.fedoraproject.org vmhost-p08-copr02.rdu-cc.fedoraproject.org vmhost-p09-copr01.rdu-cc.fedoraproject.org AddressFamily inet6 ControlPath=~/.ssh/skt_%h_%p_%r ControlMaster=auto ControlPersist=60
This way I can make Copr builders started over ipv6.
ICMPv4 to people01.fedoraproject.org fails, to people02.fedoraproject.org works.
people01.fedoraproject.org
people02.fedoraproject.org
Hm, ipv4 seems to work fine again. Closing.
Metadata Update from @praiskup: - Issue close_status updated to: Fixed - Issue status updated to: Closed (was: Open)
It is actually the same issue as the last time (fiber cut), seehttps://pagure.io/centos-infra/issue/1326#comment-887062 (and the internal ref it mentions).
Also https://status.centos.org/ mentions it as well.
