The reason we're all here, support. One of the reasons GoDaddy is a company I still use and have used for years is that they have 24/7 telephone support that's reasonably decent. I have called and gotten domain issues sorted by GoDaddy at 2 AM on a Sunday by a dude who didn't have a foreign accent.

I'm not a big account with them, surely trivial compared to those mass domain parkers you mention, but they've never made me feel like I was less valued as a customer. I have received calls from humans just to ask me if I am currently satisfied with my service with them.

Especially if you have a business-critical service, this should simply be a baseline requirement for support, but it's becoming shockingly rare these days.
