Yeah. There's no reason a site would "go dark" unless either there's no more seeders for the site (everyone deleted it off their computer, or the people who have it aren't running ZeroNet anymore) or the Namecoin .bit domain expired and no longer links to the ZeroNet address (at which point you could still access it through the long address that will never expire).

As long as someone has the page, it won't go down.
