Thanks for the comment. I work at UpCloud so I'll chip in my 2c on the issue. Your description of "how much money providers are willing to risk" is a great way to approach this. While it doesn't probably give you the most universal view on redundancy - it is a good, comparative measure of how much companies are willing to risk if their services go down.

Building multi-cloud services is of course a way to try and avoid this, but I would say that this approach isn't very well adopted as of yet.

Having said that, those utilising cloud hosting services will need to balance their own risk levels with those of the companies they are looking at and find the best match. Another way to approach this is to ask; how much am I willing to risk my business for the benefit of this company offering me a cloud hosting service?
