Yeah the account is from like 2019 or so. But still, I’m spinning everything up with Terraform or AWS Copilot, so it is still an active choice on my end to put it in us-east-1.
This wasn't an "everyone is in the US" type of post. Even for non-US folks, for a long time the default region was us-east-1, until they switched it to eu-west-1, and about 1/2 of all of AWS customers are in the US, or at least used to be until recently.
