The way it's described now is a weakness in their infrastructure of which I wonder if it's possible to prevent this from happening again.
Godaddy has plenty to lose by f-ing up. And to my knowledge (as a somewhat small competitor; I'm just pointing that out so my thoughts are taken in context) they have a fairly robust system (anecdotal) for the amount of data they manage. My issues with godaddy (as a competitor) were always on the sell side, the issues of constantly selling you things you don't need etc. Technically I really didn't have any issues with them.
