Update: The Funday PawPet Show, Megaplex, and for the Furry Costume Information Exchange have been restored.
Sites known to be affected center around the Florida Furs, and include the Funday PawPet Show, Megaplex, the Furry Costume Information Exchange (hosting the FURSUIT mailing list and an archive of fursuit-related stories), JR's Poinkcasts (also available elsewhere), and resources for furry ham radio enthusiasts.
IRC server lion.anthrochat.net is also affected. As it was the provider of IRC services for the Anthrochat network, channel and nickname registrations may be lost. The network itself remains online, and a temporary replacement is in place on another server.
