Major us-east-1 outages happened in 2011, 2015, 2017, 2020, 2021, 2023, and now again. I understand that us-east-1, N. VA, was the first DC but for fucks sake they've had HOW LONG to finish AWS and make us-east-1 not be tied to keeping AWS up.

First, not all outages are created equal, so you cannot compare them like that.

I believe the 2021 one was especially horrific because of it affecting their dns service (route53) and the outage made writes to that service impossible. This made fail overs not work etcetera so their prescribed multi region setups didn't work.

But in the end, some things will have to synchronizes their writes somewhere, right? So for dns I could see how that ends up in a single region.

AWS is bound by the same rules as everyone else in the end... The only thing they have going for them that they have a lot of money to make certain services resilient, but I'm not aware of a single system that's resilient to everything.

If AWS fully decentralized its control planes, they’d essentially be duplicating the cost structure of running multiple independent clouds and I understand that is why they don't however as long as AWS is reliant upon us-east-1 to function, they have not achieved what they claim to me. A single point of failure for IAM? Nah, no thanks.

Every AWS “global” service be it IAM, STS, CloudFormation, CloudFront, Route 53, Organizations, they all have deep ties to control systems originally built only in us-east-1/n. va.

That's poor design, after all these years. They've had time to fix this.

Until AWS fully decouples the control plane from us-east-1, the entire platform has a global dependency. Even if your data plane is fine, you still rely on IAM and STS for authentication and maybe Route 53 for DNS or failover CloudFormation or ECS for orchestration...

If any of those choke because us-east-1’s internal control systems are degraded, you’re fucked. That’s not true regional independence.
