Given they had ~300 minutes of outage in 3 years, you're looking at ~99.98% reliable in just that region. That's pretty good for a stateful serving system, and indeed you'd be pushed to do better.

From experience I think some of the problem is that not everyone appreciates the importance of correctness in this sort of system. At the very least you should clearly documenting your expected failure modes, so that it's possible to b

I think it's devolved beyond that into a marketing term, I've seen realtime mean anything from milliseconds to hours. I'd mostly interpret it as "faster than what you already have/are used to".

As well it's interesting to see the different responses of teams when problems are raised. Some are very thankful for the analysis, others don't seem to appreciate how important correctness is in this type of distributed systems.
