But.

Changing DNS registrars for a whole bunch of domains could take many hours of screwing around. If you make a mistake you might accidentally bring your site down for some amount of time. Your customers do not care at all either way anyway.

It's all disadvantages with no advantages.

Meanwhile, when you want to register a new domain, if you already have a domain with GoDaddy you may as well just go ahead and register another one on the same account. It's one less account to sign up to and deal with the credentials of, one less entry in your accounting software each year.

So yes, my company still uses GoDaddy.
