#OCPBUGS-15430	issue	13 days ago	KubeAPIDown alert rename and/or degraded status ASSIGNED
We have many guards making sure that there are always at least two instances of the kube-apiserver. If we ever reach a single kube-apiserver and it causes disruption for the clients, other alerts such as KubeAPIErrorBudgetBurn will fire. KubeAPIDown is here to make sure that Prometheus and really any client can reach the kube-apiserver, which they can even when there is only one instance of kube-apiserver running. If they can't or that availability is disrupted, `KubeAPIErrorBudgetBurn` will fire. Comment 23058588 by Marcel Härri at 2023-09-19T06:57:07.949+0000
