I've read this multiple times that AWS us-east-1 region is the one that has the highest number of outages. I am eager to hear others' experiences here.
People are just projecting their own cognitive biases.
As Werner has said before everything fails all the time, so you need to design your system/architecture to accept that constant. US-east-1 is by far the largest of the regions, and at that scale you can probably assume that at any given point in time there is hardware in there failing that needs to be physically replaced. As a result it's the region most well equipped to tolerate that level of constant failure (it's got 6 AZs!). It's also the the most popular of the regions, is typically one of the launch regions for new services, and runs a bunch of critical Amazon infra too. If anything it holds a special place in terms of importance for AWS to keep it up because the impact of a widespread problem here is amplified. For the same reason though any problem here is much more visible across the entire internet. Which is why the handful of outages are so memorable to people.
It’s not that the oldest hardware is moved there, it’s just that the oldest hardware was there to begin with. There are probably still first-generation EC2 instances running in us-east-1 on their original platforms.
