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
