No...I understand that and that is a very salient point. However narrowing down the cause to something that aids the rest of us is not bad thing. I don't expect IP addresses and machine names but a general statement of whether it was power or bad code which has been rectified is not a bad thing.
Bearing in mind that we have such controversy surrounding "cloud" there has to be some level of openness when the shit hits the fan. I mean..if I am going to entrust my data to a third party I certainly want to know what went wrong at some level...not a statement that "we did a root cause" with nothing else. So I reckon it also makes commercial sense to have some transparency. Even if they said that effected companies have been given full details of the root cause analysis would have been fine.
When I worked for a major storage vendor the one thing that was drummed into us as technical support managers was to be as honest and open with our customers in the event of outages. We managed to get a pretty good reputation for providing not only top notch support but honesty (well as far as tech support was concerned) as well.
