For those of us who have been using AWS for almost 20 years now, I can't imagine why anyone would willingly choose us-east-1 for anything. It is the oldest, highest traffic, most critical path region and is subject to turbulence.

I think it is a little complicated. For example, your service might be using full failover but you use API from other service which are down.

Or you might use BART to come to work and you got stuck: https://www.kqed.org/news/12060687/bart-resumes-service-but-...

ha! I saw another comment on here talking about how ec2 doesn't need to be held to the same standard as the power company because it's not as important as real infrastructure.

wish I'd already had this link in my back pocket. our industry needs to take its job, as a whole, much more seriously.

“Global” and “edge” services such as IAM, Route53, CloudFront and so on have dependencies on us-east-1, so even if you don’t think you do, you probably do.

By some logic, that would mean it is the most battle-tested and highest-stakes (and therefore most carefully-managed) choice. I.e. reasons in favor.

Not that I disagree with you, but maybe not for the reasons you say (:

As someone who used to work on the inside, us-east-1 has the biggest pile of legacy workarounds for internal AWS issues, it has a variety of legacy API behaviours that don't exist in other regions, and because everyone picks it as the default, it has significantly more pressure on contested resources (i.e. things like spot instance pools).

Plus since it's the default in all the tooling, if you ever decide to go multi-region, you'll find tons of things break right away.

Well, we didn't, but some of our third party softwares did. Hard to avoid.

It can make sense to depend on the thing that will attract massive worldwide attention if/when it goes down. Or, more likely, it's just a default people don't change.
