How to handle domains? The rest is easy, but your domain registrar blocking you sounds like a pain. My current solution is to use a local small provider, just for the domain. Then if there is a problem with your play account it is out of any blast radius.
What do you mean by local small provider? A registrar on main street?
What the deuce are you blathering on about. An account got blocked, this has nothing to do with a domain.
And I’m talking about having disparate failovers that don’t rely on a single hosting provider. At that point, who cares what Google does to your cloud account… work with the hot failover and spin up another hot failover somewhere else.
