Having had my primary Gmail account blocked twice in the last two months, apparently through VPN usage, I became sufficiently terrified to decide to start to move all my email to my own domain.
I adopted Fastmail for my domain email, and it has been a good experience (I do know that Fastmail is a five-eyes company with all the related issues around privacy, and I researched alternatives for several weeks, but I guess in the end I was willing to trade privacy for ease-of-use, uptime and various other factors).
Now I am looking into getting away from other Cloud-provided backups such as Prime Photos, iCloud, etc., moving to self-hosted NAS storage.
