Dropbox damage should have been limited, wasn't
In response to Number 6, I would have to agree that DropBox has a good record, but if you look at the Twitter comments on the outage, you can see doubt creeping into some of its users' confidence in their offsite storage supplier. And on one important point, the explanation for the outage is not an explanation. The updating of the operating system in some database master/slave combinations resulted in all three systems being lost. They then had to be reconstructed from backup, as I read the explanation. Any one who reads this differently is welcome to explain a different interpretation. But my position is, this isn't supposed to happen in the cloud. The cloud software allows for, and compensates for the failure of any one component and the service as a whole keeps running. The damage from what went wrong at Dropbox should have been contained, but it wasn't.
