It looks like your best bet for higher availability for masters is to set up your own cluster with multiple masters on top of GCE with kubeadm or similar tools.

Such an outage may impact one or multiple services, and both cases may or may not impact availability of a GKE master. Moreover, I don't think there has been natural disasters that impacted an entire zone in the history of public cloud; however that is not an indicator of likeliness of a natural disaster happening. If you think GKE master as a Compute instance running on a zone the SLA is 99.95% (https://cloud.google.com/compute/sla) uptime (downtime is defined by period of >1 consecutive minute). > >> Thanks for your help in advance. >> >> -- >> You received this message because you are subscribed to the Google Groups >> "Kubernetes user discussion and Q&A" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to kubernetes-users+unsubscr...@googlegroups.com. >> To post to this group, send email to kubernetes-users@googlegroups.com. >> Visit this group at https://groups.google.com/group/kubernetes-users. >> For more options, visit https://groups.google.com/d/optout. >> > > -- > You received this message because you are subscribed to the Google Groups > "Kubernetes user discussion and Q&A" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to kubernetes-users+unsubscr...@googlegroups.com. > To post to this group, send email to kubernetes-users@googlegroups.com. > Visit this group at https://groups.google.com/group/kubernetes-users. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Kubernetes user discussion and Q&A" group.
