It is good to see that Amazon released a pretty detailed statement detailing the events of the S3 outage on 7/20.  Some people have been complaining about the stability of the environment, but I think it has been overall really good.  When there are problems they are fixed extremely quickly and if there was going to be any delays they kept everybody up to date.  I think the Service Health Dashboard is great information tool.  I may not be happy when there is a problem, but atleast I don’t feel like I am in the dark like I have in the past with some other hosts/service providors.
