 Replying to [comment:2 johnbillion]:
 > My only guess to the cause of this is that MYSQL is caching the results
 in the query cache even though the query contains `RAND()`. I've never
 heard of this happening though.

 That'd be strange indeed. Keywords such as NOW(), CURRENT_TIMESTAMP() and
 RAND() are all by-pass query cache. If I had to guess, I'd say that maybe
 the 2/10 servers have page cache enabled, or perhaps the results of
 `WP_Query` are being stored into persistent object cache. In any case,
 need more details.
