Two 9s of availability? Half the customers I've had would be ecstatic to have even ONE 9 of availability. And those guys hardly ever ship any code due to how encumbered developers typically are in those places and release maybe once every 6 months to a year perhaps. In fact, this is basically my typical experience with most enterprise customers I've worked with as a consultant - they're unable to execute almost anything materially important and customers put up with them because nobody else is in that niche enterprise market that's keeping people employed by lack of choice / market consolidation (healthcare.gov is just a visible example - plenty more projects are even worse with perhaps even larger budgets with zero media attention).
