ZFSBootMenu Down?

Documentation pages work but can’t download ZFSBootMenu

curl -L https://get.zfsbootmenu.org/source | tar -zxv --strip-components=1 -f -
returns:-
curl: (7) Failed to connect to get.zfsbootmenu.org port 443 after 199 ms: Couldn’t connect to server

Part way though a 23.10 build

Am I having a DNS problem?

ping get.zfsbootmenu.org
PING get.zfsbootmenu.org (75.102.1.121) 56(84) bytes of data.
64 bytes from stratumzero.date (75.102.1.121): icmp_seq=1 ttl=53 time=212 ms

Yeah, it looks to be down from here as well. How about using the releases page on GitHub? Maybe the file you need is there.
