That's an over generalization. And difficult and expensive relative to what? When evaluating the cost of solutions to problems like this, the basic idea is to compare the cost of the solution and the cost of the problem (if realized) with the likelihood of the problem being realized factored in. It's quite possible Bitbucket will cease to exist if they continue to have problems like this. I'm sure their customers are not happy. It does sound like they have plans to fix this once they get back up and running.
