[ale] news.google.com affecting BIND and Drupal?

Tue May 24 15:20:14 EDT 2011

news.l.google.com implements DNS round robin plus some sort of
localization feature (I'm not sure what, but it always gives results
in the same /24 to a single query.)

I don't see anything significantly different in your queries.  (And,
to be honest, I'm not sure how Drupal factors in at all.)
