>99.5% uptime is good enough for nearly all businesses.
I don't know what your business is, but as a presales engineer in the ecommerce field, if our SLA was 99.5% we wouldn't even make it past the first round of vendor selection.

As you know, the SLA isn't the same as the downtime. It just means the threshhold where you'd start paying back some credits for missing the SLA (only to customers who notice and ask). Which is often cheaper than building the infrastructure to actually support the promised SLA.
You can also have different levels of avaibility for your customer facing and critical infrastructure and the infrastructure running your internal services and less important stuff. No need to have a bunch of 9's for your internal test environment or for the systems managing app deployments to the fleet of internal laptops.
Our customer contracts obligate us to inform all customers about any outages. We can’t just hope they don’t notice and only pay the ones that happen to.
Out of curiosity, how do you handle cases where the cloud provider lies to you on their status page? Do you pass on the lie to your customers or do you have your own monitoring in place?
