Trying to understand on which scenarios all the instances of an application running from cluster unavailable?
OS upgrade failure??
Openshift upgrade bugs/failures/downtime?
Router failures ??
Keepalive containers failed??
Floating IP shared by keepalive container had issues??
VXLAN bug or upgrade caused entire cluster network failure?
Human config error ( what those???)
Is above list accurate? Can we think off any other possible scanarios where whole application will be down in cluster duet to platform issues?
