Interesting, thanks for that. I'm up and running on my own domain after waiting for the domain name server to transfer from Bluehost where I registered the domain. I did start out doing manual configuration until deciding I might as well use Fastmail's; their DNS config page is rather nicely laid out.

Was very easy in the end, but must admit I had forgotten just about everything I once learned about DNS. As such it was nice to get a little refresher.

EDIT: I would probably have gone for Google Apps / G Suite if not for this article. So, yeah, hope it served Google well to freeze those accounts with no warning.
