Twitter and Facebook always show as "appears incorrect"

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run namebench with default settings, using a browser history with lots of 
activity on Facebook and Twitter

What is the expected output? What do you see instead?

Expected: Twitter and Facebook do not "appear incorrect", or at least not 
always.

Actual:
* twitter.com appears incorrect: 199.59.148.83, 199.59.148.10, 199.59.148.82
* www.facebook.com appears incorrect: 69.171.224.39

on every single listed DNS server (IPs differ, though)

What version of the product are you using? On what operating system?

Windows 7 64-bit

Please provide any additional information below.

I suspect this is due to some load-balancing technology your program isn't 
correctly handling.

Issue could also be regional/geographic DNS entries for these sites. I don't 
think this is anything to do with load balancing. There seems to be some 
nameserver which namebench assumes is authoritative for twitter/google/facebook 
which disagrees with the bulk of the nameservers queried during testing.

My system's Windows 7 Home Premium shows the same message alerts (for all DNS 
tested) for twitter, google.com, and facebook.  I've never used Twitter nor 
Facebook.
