Not fastmail, but I was going to migrate to https://porkbun.com/. Put it on hold because of issues (which I see is now down to the 72 hour delay) and domain renewals coming up.
I heard of porkbun as well, but haven't tried yet. Seems like all in one.
So far my registrar is Gandi (don't have enough reason to change it), DNS server is CloudFlare, websites are GH pages and mails will be FastMail so it seems.
