It's really good machine sympathy for keeping the unfunded service cheap to run, but it's one bad fan bearing away from losing a lot of messages, so I wouldn't say its design assures four nines. And the optimization work to get all the way down to n=1 wouldn't have paid off if Tyma needed to hire someone at market rate to build that and maintain it, because an engineer-month costs hundreds of instance-months.
