90% of the customers were just preauthorized and never charged. It wasn't a 7.5 million dollar mistake. Overall, this sort of thing has happened at GoDaddy a couple years ago and Hostgator.
Neither host ever publicly admitted it to all of their customers. You shouldn't down a company for it - you should be appreciative they are honest enough to admit their mistakes.
This looks more like a plug for G**KRack than actually a topic about Dreamhost
As for joking about it: If you have read any post that DH has ever put up, it is common knowledge, that is just Josh. Dreamhost is known for their charisma and upbeat attitude, no matter the situation. If they weren't many customers would be much more concerned. Excellent company with excellent support and absolutely one of the most honest hosts out there. Mistakes happen. Just because they have 150k+ clients doesn't mean they won't make mistakes either. 10 Years in the business without a billing error that overcharged, until now? Guaranteed - most of you will wish you have the same record. I sure hope I do.
