Frequently Asked Questions

What is the URL for the Single Sign-On Console?#

Answer: Login using your CU IdentiKey at https://aws.colorado.edu.

What region should I use?#

Answer: The us-west-2 AWS region has the lowest latency from Colorado’s Front Range region (CU Campuses) and is the only region supported for VPN connectivity to the Boulder campus.

Why do I get errors using Non-US regions?#

Answer: By default, access is restricted to US regions only for confidential workloads. You will see API errors trying to access Non-US regions. If you need access to a Non-US region, reach out to rc-help@colorado.edu, and we can evaluate the possibility to operate in Non-US regions. See AWS Restricted Regions.

Why can’t I see the AWS resources I created?#

Answer: Be sure that you have selected the correct AWS region. Many AWS services are region specific. Also make sure you are logged in to the correct AWS account with the correct Role.

Can I use the root user?#

Answer: No. The root user is owned by the Research Computing Cloud Foundation team. You must use your CustomerAdmin role.

How do I close my AWS account?#

Answer: Send an email to rc-help@colorado.edu and provide the account number or account alias for the AWS Account you wish to close. Be sure to leave your PO open for 2 billing cycles after the account has been closed to make sure there are no further charges before closing your PO.
