When is the last time they had a single service outage in a single region? How about in a single AZ in a single region? Struggling to find a lot of headline stories? I'm willing to bet it's happened in the last 2 years and yet I don't see many news articles about it... so I'd say if the only thing that hits the front page is a complete region outage for 6+ hours, it's working out pretty well for them.
