The whole site will go static, that includes the ULA list.

The ULA registry was always a inside-joke as they are randomly generated
they should never collide.

As the page states:
ULAs were not intended to be registered in any way, it could still be
that somebody generates the same prefix and when not checking here, they
might use it.

People who have a need for a globally unique registered prefix, should
go to the RIRs where they can get one.

Page also notes:
This file can be cached by other entities, solving any reachability
issues, and for archival and redundancy purposes. We hope that one day
either IANA/NRO can serve a similar list along with whois and DNS
delegations and will provide them full assistance to do so when the time

Thus plead with them to take it over. I am fairly confident they will
point people to the RIRs though.
