The DSL provider for FurryMUCK, the first furry MUD and largest MUCK on the Internet, has gone out of business and shut off services. I haven't seen an alt.fan.furry or aff.muck post about it yet.
I would also like to point out that while Flayrah.com is a good source for furry news, they don't cover MUCKs, which would be nice since there's no Slashdot for the MUCK community.
