Yes, the first one was my router. Which itself is configured to use Google anyway. Of course, it's strange that EoFF is (as far as I can tell) the only address to have problems. Everything else works fine.
UPDATE: It actually seems that any domain using the same dns servers as EoFF sees the same behavior. Since this appears to mostly be a bunch of no-name sites, no wonder I wouldn't notice. Therefore, I must hypothesize that this is a communication problem between some of google's DNS servers and the godaddy dns servers. Presumably it will resolve someday if someone notices. I have no idea if this information applies to Aaron's problem whatsoever.
