I think amazon is approaching this in the right fashion - when you have a major outage, show that you understand exactly what the issue is, and why it won't happen in the future. That's quite a while to be down, but their openness, and what I perceive as honesty, helps me trust that they know what they're doing. And like mixmax said, their detailed description and timeline scores them extra points, instead of the usual corporate nothingness. We're still planning on moving over to "cloud-computing", or "infrastructure-outsourcing", and AWS still seems to be the leader in the field.
