MODERATORS
The whole point of status pages is to minimize and deflate the impact. The pleasantly-high percentages even during absolute catastrophes is an intentional design feature. The percentages are not going anywhere. The percentages will continue until reliability improves. Which it won't.
a "large" number like 99.999% looks impressive, and 99.9999% is more impressive
Idea: if we run two servers, we could count as 199.9998% !!! /s
Anyone who is actually responsible for the uptime of anything understands the difference between 3 nines and 4 nines and how significant it is to gain or lose a nine.
I thing the first nines are most important (9% vs 99%)
The first nine would 90% then it would go straight to 0%
