In a prior post I implemented this AWS Service Control Policy which restricts actions to specific regions:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Deny",
"Action": "*",
"Resource": "*",
"Condition": {
"StringNotEquals": {
"aws:RequestedRegion": [
"us-west-1",
"us-west-2"
]
}
}
}
]
}
It used to work. Today I was trying to use some of the global services in my account and getting errors on things like AWS S3 and CloudWatch.
Need to figure out if there is a way to restrict regions while allowing the global services now unless AWS rolls this back. It doesn’t really make sense. Thank goodness I could still login, since IAM is a global service.
Note: I later think this may have been caused by VPC Endpoints or some other issue. In any case the region SCP is working. It would help to have very clear error messages explaining what the problem is when connections aren’t working.
