As a PaaS vendor, they are supposed to abstract away from IaaS failures. And they were not to use a single region to host all their apps. I love Heroku and will continue to use them as long as I have the option to add affinity to my dynos and workers to spread across multiple regions of my choice. Coupled with anycast DNS support, this will be a very compelling offering, if they can pull it off. During the outage, all of our scale engines (http://blitz.io) and our CouchDB cluster across the other AWS regions held up, but since the web-tier was down, the whole app went down.
