Basically, we commit to 99.9% uptime, measured on a monthly basis. If an S3 call fails (by returning a ServiceUnavailable or InternalError result) this counts against the uptime. If the resulting uptime is less than 99%, you can apply for a service credit of 25% of your total S3 charges for the month. If the uptime is 99% but less than 99.9%, you can apply for a service credit of 10% of your S3 charges.
Very nice to see this shortly after the AWS presentation by Jeff Barr at the Berlin Ruby User Group. But I guess that for many people in big corporate settings this is not enough. But still, it's a start. And it makes selling AWS S3 as part of our solutions easier.
I'n now waiting for a EC2 SLA.
