I'd like to point out that jelastic.com Kubernetes services are very helpful for webmasters and webdevelopers. The Kubernetes control plane consists of various components, each its own process, that can run both on a single primary node or on multiple primaries supporting high-availability clusters. So, TOP recommendation for using their service.
So far i haven`t noticed any downtime. I guess there should be but it was so small i didn`t notice it. Libertyvps.net tech support is second to none. All tickets are resolved in 15-20 mins. This comes to a price. It`s not the cheapest host.
