I'm not sure S3 has changed nearly as much as the rest of AWS, which is probably why it is so stable. Regardless, the point is that outages can happen to S3 as well, and have; just because it hasn't happened for a few years doesn't mean than 99.99% = 100%.

In fairness high availability is usually measure per annum, on that metric S3 is 100% for the last 5 years.

Also a few years doesn't really imply 6 years to me.
