AWS tries to lock people in to specific services now which makes it really difficult to migrate. It also takes a while before you get to the tipping point where hosting your own is more financially viable .. and then if you trying migrating, you're stuck using so many of their services you can't even do cost comparisons.
"After a 2012 storm-related power outage at Amazon during which Netflix suffered through three hours of downtime, a Netflix engineer noted that the company had begun to work with Amazon to eliminate “single points of failure that cause region-wide outages.” They understood it was the company’s responsibility to ensure Netflix was available to entertain their customers no matter what. It would not suffice to blame their cloud provider when someone could not relax and watch a movie at the end of a long day."

For the downvoters, please just link here the proof if you disagree.
Here are the S3 numbers: https://aws.amazon.com/s3/sla/
I understand this is long-since resolved (I haven't tried building a service on Amazon in a couple years, so this isn't personal experience), but centralized failure modes in decentralized systems can persist longer than you might expect.
(Work for Google, not on Cloud or anything related to this outage that I'm aware of, I have no knowledge other than reading the linked outage page.)
Maybe you mean region, because there is no way that AWS tools were ever hosted out of a single zone (of which there are 4 in us-east-1). In fact, as of a few years ago, the web interface wasn’t even a single tool, so it’s unlikely that there was a global outage for all the tools.
And if this was later than 2012, even more unlikely, since Amazon retail was running on EC2 among other services at that point. Any outage would be for a few hours, at most.
"Some services, such as IAM, do not support Regions; therefore, their endpoints do not include a Region."
There was a partial outage maybe a month and a half ago where our typical AWS Console links didn't work but another region did. My understanding is that if that outage were in us-east-1 then making changes to IAM roles wouldn't have worked.
