I might have missed it in the search, but seems Hetzner is probably still working on it. Nobody here like to deploy k8s although the tools to do that are super sexy these days.
But certainly for SEA they don't make sense, unless you e.g. have any subsets of functionality that are bandwidth intensive but not latency insensitive (e.g. I used to manage a network that was split between UK, Germany and New Zealand, and we used Hetzner for the German footprint and put anything where latency didn't matter, like bulk e-mailing, there, while customer facing stuff was all in their respective country). For that to be worthwhile you need a quite significant volume though.
