+1 Sorry to be the monday morning quarterback, but the sites that went down learned a valuable lesson in single point of failure analysis. A highly redundant and professionally run data center is a single point of failure. Geo-redundancy is key. In fact, i would take distributed data centers over RAID, UPS, or any other "fancy pants" © mechanisms any day. And, aws East also seems to be cursed. I would run out of west for a while. :-) I would also look into clouds of clouds. ... Who knows. Amazon could have an Enron moment, at which point a corporate entity with a tax id is now a single point of failure. Pay your money, take your chances. CB
