No idea which blog causes it.

I can't reproduce this. If I try to go to this URL in my browser I get redirected a couple of times then a Connection Refused.

TumblThree just typical handled System.Net.WebExceptions and no NullReferenceException unfortunately.

Any other examples? What happens if you go to this URL in your browser from your location? What country are you accessing it from?
