ARIN RPKI ROA Hybrid System

Hey all, first post here at NANOG! Hope I’m doing this right?

Just curious if anyone has further information about ARIN’s RPKI ROA Hybrid System. It’s still delegated, but instead of requiring your institution to host the CA, repo and publisher, ARIN takes over the repo and publisher, making it much easier to mange as all that is required is the CA.
I had heard a date around 12/15/21, and here it’s today, but haven’t found anything on it.
Anyone else know more about it?

Thanks, Chuck
