It's an open offer. Do they support python?
edit: they do, but it's not clear how to easily deploy a multi-zone application. Could you point me towards some docs?
Right now any single app can be deployed from any one of a bunch of infrastructures, AppFog is working on the ability to run one app in multiple infrastructures simultaneously too.
appfog.com also has outages as well - http://blog.appfog.com/october-27th-downtime-postmortem/ - when going with public cloud, your app's well being is always in 3rd party hands. If you want to mitigate the risk, host your own private PaaS on your own infrastructure - then you can only point your finger at yourself when outages occur.
