"Starting on February 22, 2024, you can no longer use Google Groups
(at
groups.google.com) to post content to Usenet groups, subscribe
to Usenet groups, or view new Usenet content. You can continue to
view and search for historical Usenet content posted before February
22, 2024 on Google Groups.
In addition, Google’s Network News Transfer Protocol (NNTP) server
and associated peering will no longer be available, meaning Google
will not support serving new Usenet content or exchanging content
with other NNTP servers.
This change will not impact any non-Usenet content on Google Groups,
including all user and organization-created groups. Most of the
current Google Groups content is not Usenet content and will not
be affected."
