Do positive DNS tests
yep. do we do some 'positive' dns tests too? that is, if we can't resolve google or cnn or akamai, maybe we can't resolve anything. mikeperry found some relays that can't resolve anything
Maybe we should add some more tests to see if some well-known sites can be resolved. Also, we should probably wait with publishing the descriptor until DNS tests have run.
