I can probably help for that 🙂

AFAIK the ec2 instances in the .centos.org domain are all tagged though, so do you have a list of ec2 instances/volumes that are really from centos and not tagged properly ? In a previous mail I saw something like "centos stream builders" mentioned but there are zero centos stream builders in public space like aws (for obvious reasons as they are internals)

I found some centos stuff not tagged:

Region: us-east-2

instances:

* N/A (i-07678cd3d615ca52a, N/A)

* N/A (i-0278bbf7d7b9801b2, N/A)

Volumes

* vol-0bd20acb90dcaa116 N/A (, N/A)

vol-07fa6789322a53ee1
