foo.gentoo.org fails DNS resolution when checked from two completely separate DNS servers in Germany, one inhouse (NAT'ed behind 145.254.194.93) and one inside the University of Marburg (137.248.123.2). There's obviously nothing wrong with your services or I wouldn't be able to post this bug report *grin*, but I thought you'd like to know that they're currently unreachable from (at least parts of) Germany.
I did look into this -- we have a web server in germany (kite.gentoo.org) and I was able to successfully resolve all *.gentoo.org domain names that I tried from that box. ulrich -- if you're still having problems, please contact me via email and we'll get it worked out. Otherwise, closing this bug.
