plerd-users: 404 Not Found

[jdalbey]

Apologies if this is off topic.
It seems the plerd-users mailing list is missing.
The 2018-09-16 blog post on Fogknife introduces mailing lists and gives this URL: http://lists.jmac.org/listinfo/plerd-users
Today that URL gives a 404. Has that mailing list been discontinued?
