Earlier this month, we announced that you can now opt in to receive longer format resource IDs before the permanent switch to longer IDs after June 2018. Today, we are publishing AMIs with longer IDs for you to use to test your systems. These are secondary versions of existing AMIs to be used for testing purposes only:

  • TestLongIDs - Microsoft Windows Server 2016 Base
  • TestLongIDs - Microsoft Windows Server 2012 R2 Base
  • amzn-ami-hvm-2017.09.1-longidtest.20171120-x86_64-s3

Systems that parse or store resource IDs may not work with longer IDs. We strongly recommend that you test your systems in preparation for the switch to longer IDs after June 2018. Additional information including details of how to test your systems and access these AMIs can be found in the FAQs and EC2 documentation.
