>Oct 20 12:51 AM PDT We can confirm increased error rates and latencies for multiple AWS Services in the US-EAST-1 Region. This issue may also be affecting Case Creation through the AWS Support Center or the Support API. We are actively engaged and working to both mitigate the issue and understand root cause. We will provide an update in 45 minutes, or sooner if we have additional information to share.

Weird that case creation uses the same region as the case you'd like to create for.

The support apis only exist in us-east-1, iirc. It’s a “global” service like IAM, but that usually means modifications to things have to go through us-east-1 even if they let you pull the data out elsewhere.
