Amazon S3 now has a Service Level Agreement

Jeff Barr says:

I am very happy to announce that, effective October 1, 2007, The Amazon S3 Service Level Agreement is in effect.

Great news! And it's about time.

The general gist:

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.

A good step in the right direction. Now if we can get this on EC2, we're golden.
