Google fucked around too long for me to consider using any of their new services and I'm working on dropping the old. Got bit in the ass with Allo, Hangouts, GPM, Inbox, and latestly Domains, which I thought was safe.
Yeah getting dependent on any Google service is just a waiting game to handle catastrophe. That said I've yet to find a single semi-competent calendar widget in Android (month view most importantly) which keeps me. But as the legacy workspaces fiasco showed it's only a matter of time until I'm forced to take action.
I just moved mine to namecheap & am using cloudflare dns instead of Google cloud dns. Had to setup my email forwarding and my ssl certificate renewal again but otherwise rather painless.
Namecheap's website loads pretty slow but their support is top notch. The chat button on the page will immediately connect you to somebody that actually knows the product which is nice.
