I'd suggest "You live by the cloud, you die by the cloud", and everything else falls to contract law. Have your lawyer read your agreement carefully.
I like some of the emphasis on physical location of the data store. I'd like to store my data in the country with the strongest privacy laws, please.
What's wrong with making known physical location a service that you buy, rather than a right? A right is really just a service that you can't not buy.
As a cloud service provider, it paints you stupid. At least for potential European customers. We can't store personal information about clients outside EU. Storing that kind of data in the cloud, without knowing where it... roams is a liability. Not helping your clients avoid liability makes for very bad business practice, hence you're stupid (CSP (Cloud Service Provider)).
