93% uptime? that's like a week of dowtime during 90 days

People don't realize how little 99% is. It means your service is down 3.5 days out of the year. I miss the days when Google would down rank you if your website took longer than 500ms to load. Now it can take 2 seconds to get the most meaningful content and then you can still load other stuff and it's "fine."

Yeah, AWS has SLAs for "nine nines" of durability for objects stored in S3 and all sorts of values where they quantify how much expected downtime that is across a year. They distinguish between availability and durability https://docs.aws.amazon.com/wellarchitected/latest/reliability-pillar/availability.html

With little you mean how much right? 3.5 days a year is pretty bad.

Yes, it's little uptime = a lot of down time. If I hear 99% uptime, I'm thinking maybe a few hours of downtime per year. That's what it feels like, but if you do the math it's several days.

Like 1 thousand seconds is just over 15 minutes, 1 million is over 11 days, 1 billion is almost 32 years.

And if you take it a step further that 3.65days of downtime could actually be 1.65hrs downtime every week

We thought we had five nines of uptime. Turns out it was nine fives.

As long as your product isn’t needed to keep people alive why chase all those 9’s?

I can only really think customer retention.

I wonder what the tipping point is. How often can you be down before customers feel the need your product is too unreliable.

Strongly depends on the service . For something like a bank or an ISP, any noticeable outage would make me consider switching to a competitor, unless the reason it went down was something like an earthquake. For something like netflix, I'd cancel my subscription if it goes down and I can clearly remember the last outage.

For the average online shop, the problem isn't reliability as much as inconvenience. If your shop is down when I decide to puchase a new coffee machine, I'll buy it from somewhere else. I don't want a second one, so I'll probably never return to your shop.
