I use Open DNS, yet several times today I have the 404 error "Server not found" or whatever and then I get a page stating ClearCloud DNS is shutting down. Happened trying to log into here once too. Anyone else experiencing this? Thank you! I'm editing: My router's Tomato firmware GUI has three DNS fields. My third choice, after the two Open DNS servers may have been ClearCloud. I've replaced it with Google's.
