Why is OpenDNS redirecting Google?

bradt writes: Yesterday, a friend suggested that I check out OpenDNS.com as a way to "speed up" my internet connection... I did a few DNS lookups with dig to see if they were faster than my ISP, and discovered that OpenDNS is redirecting www.google.com to their domain! It seems that this issue has been going on for at least a month, and has been discussed in the OpenDNS Forum and in Google Groups as well.
