Webcomicsnation

Does anyone know what's going on with www.webcomicsnation.com? Yesterday, I kept getting warnings that the site was suspect (although the evidence supplied was entirely negative); today I get a 404. Since they host three of the webcomics I regularly read ("Breakfast of the Gods", "Narbonic Director's Cut", and "Skin Horse"), I find this distressing. (I was hoping that Shaenon Garrity's LJ would say something - she writes the latter two comics - but so far there's nothing from that quarter.)
