Yes. to put it a bit bluntly, you are using a very generic google search and being blind to nuance.

us-east-1 does have more problems than other zones due to a variety of reasons, but it rarely (ie, once a few years) goes down as a whole. As long as you're in several AZs within us-east-1, the impact of most outages should not take you down completely. In the context of the comment you are replying to, your google search links are lazy and fail to see the big picture.
