Amazon now offers an SLA for S3

Post ImageAmazon announced on Monday the launch of an SLA, or Service Level Agreement, for the S3 web service. The lack of an SLA has always been cited as a “shortcoming” of S3, but I don’t know exactly how many customers have requested it. Enough for them to offer it I guess:

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.

The SLA is effective as of October 1st, 2007. Jeff makes it sound like they had planned to have an SLA for a long time, but I’m not so sure that’s the case. Doesn’t matter now, they have one!

I think SmugMug’s Don MacAskill makes a good point:

Everything fails sometimes.

The SLA payment is rarely comparable to the pain and suffering your customers had to deal with.

Very true. From my perspective, the SLA isn’t a big deal. I hope it helps Amazon land some more customers though!
