Cloud hosting mishaps...

Cloud hosting has been around for awhile now. It's touted as the wave of the future. I understand that there will be Notebooks soon released running the Andriod OS which actually store all of your data in the cloud. How safe is it? Well, I guess that depends on who you talk to.
Of course the idea is scaleability, and copies of your data are stored on multiple platters and it's supposedly always available. WRONG!@%#&
Amazon recently had a "mishap" which took 5 days to restore services to all customers. From an article in eWeek it says:
The mishap caused disruptions in its EC2 (Elastic Compute Cloud) hosting service, knocking thousands of Websites—including such popular ones as Foursquare, Reddit, Quora and Hootsuite—off the Internet. A limited number of customers still were reporting data being "stuck" in its EBS (Elastic Block Storage) service on April 25.
Income that AWS-hosted businesses lost during that one- to five-day window of time will never be regained. This was a serious business problem for hundreds, perhaps thousands of IT managers, who are now wondering whether to continue using the service.
Of course there have been several spins on this where the responsibility of the mishap was proved to be clearly the end user and not Amazon...
O'Reilly Media's, George Reese said, "In short, if your systems failed in the Amazon cloud this week, it wasn't Amazon's fault..."
There are other people quoted in the article where they all pass the buck. Actually when you reach the end of the article you can see some comments posted to the story from people who are wondering where the buck stops ;-)
But here is something to think about. If the crash occurs when data is being written to several platters, what is the chance that the recovery is going to be 100%?
I can answer that because I have a client using a hosting company where your websites are stored in the cloud. Recovery isn't always 100%, and if they have to restore the site from backup, chances are there are going to be some errors.
