I loved Usenet back in the day, but I sort of wonder why organisations keep their servers running. I struggle to find any active newsgroups these days. Weirdly enough spam still hits some of the groups.
I used Gmane[1] to access mailing lists as newsgroups, which I've always thought was a much better fit.
Alas as with all good things that was shut down also.
A great service, glad to see it alive and kicking!
news.gmane.io has always worked.
The issue is that the owner of that domain made a mistake and gave the control of the web frontend to someone else who just shut it down.
