DNS is *not* the place to insert a search page, when an error occurs. There is a reason errors occur – to let the client computer know something is wrong. It is not simple to ‘guess’ that something is wrong since you idiots at Time warner cable and OpenDNS.org seem to think “oh, they must have typed something wrong.” No, I didn’t! And it shouldn’t be failing in the first place! It’s a perfectly valid lookup! Why your servers respond with fails for 3 out of 10 times for the same request is beyond my understanding!
