they probably have different clusters for different use cases: att big companies, this will lead to a very long tail of small clusters.
cassandra struggles to scale horizontally after a while so i am guessing that they also do some sort of application level sharding across multiple clusters
I know you might not be interested in anything chromium-based since this thread is about firefox, but qutebrowser[1] is a great solution for anybody looking for vimium/pentadactyl-like experience.
A very interesting follow-up to an insightful post. I think the answer might lie in why the american business culture is more efficient in the first place.

More law and protection has the same effect as more code: it slows things down because it increases dramatically the amount of requirements you have to contend with. A double edged sword indeed!
Your computation is incorrect, 3 days out of 365 is 1% of downtime, not 0.1%. I believe your error stems from reporting .1% as 0.1. Indeed:
0.001 (.1%) * 8760 (365d*24h) = 8.76h
Alternatively, the common industry standard in infrastructure (the place I work at at least,) is 4 nines, so 99.99% availability, which is around 52 mins a year or 4 mins a month iirc. There's not as much room as you'd think! :)
