All of the servers (co-located: so old school amiright!?) are gone and domain names have been relinquished.

I'm honestly not sure why the current webring.com has a history section on it since the site doesn't appear to anything else useful.

Just occurred to me that, if you were designing this today, you wouldn't choose "webring.com" ...

It would be Ringz.io, or wbr.ng or Loop.ly or somesuch :)
