In February 2018, AWS announced the migration of Resource IDs to longer format. Post June 2018, all the new resources will be created with longer IDs by default.[1]
This email is to announce that the Fedora AMIs has been migrated to the longer resource IDs format. The new format will migrate from the current 8-character string to a 17-character string. For example, if the AMI IDs are like "ami-1234abc0", post the migration the AMI IDs would be like "ami-1234567890abcdef0".
If you have any questions, drop an email to the list or drop in #fedora-atomic or #fedora-cloud on Freenode IRC.
