That's only a big issue when you outsource to the cheapest bidder who saves money by not testing properly and has high turnover due to low wages, so the people who wrote the software have long gone by the time the bugs hit, and no-one knows how the code works any more when they need to fix it.
Plenty of companies have huge IT infrastructure without these kind of problems. Netflix, for example, has a policy of constant testing by randomly making its servers crash and ensuring that nothing bad happens when they do. As I understand it, the only thing they're 100% reliant on is Amazon staying up in at least one region of the world.
