For what it's worth: as a Fastmail employee, it's also extremely irritating for us!
It's not bottom of the barrel outsourced "customer service" designed to point people to FAQ articles. It's professionals who work as professionals.
I'm sticking with Fastmail for now.
And in times like today, it's so nice to be able to say "hey, $person_working_now, could you deal with fastmailstatus.com and Twitter please?" and the engineering staff don't even have to think about it!
