Authentication in Non-U.S. Regions

[tonyerwin]

Hi, All,

Since about September I'm been successfully running AWS EC2 private instances from 9 different regions (us-east-1, us-west-1, us-west-2, eu-central-1, eu-west,1, ap-northeast-1, ap-southeast-1, ap-southeast-2, sa-east-1). However, about Jan 7, all of my non-U.S. regions started failing. I see lots of errors like these in the error log for non-U.S. regions:

01:40:03 - EC2:Launching EC2 instance. Region: ap-northeast-1, AMI: ami-27b28026, error: AWS was not able to validate the provided access credentials
01:40:04 - EC2:Launching EC2 instance. Region: sa-east-1, AMI: ami-eda611f0, error: AWS was not able to validate the provided access credentials

01:45:06 - EC2:Launching EC2 instance. Region: sa-east-1, AMI: ami-eda611f0, error: AWS was not able to validate the provided access credentials

Any ideas?

Thanks,
Tony

FWIW, authentication to non-U.S. regions started working again not terribly long after I posted my message. No known reason why it stopped working for a few days or why it started working again.
