I was trying to diagnose some issues with ASP.NET Web Forms post backs so I turned off IPv6 even though none of my websites were bound to IPv6 addresses. I unchecked it on the adapter property page. I had no logical reason for doing this. Then Windows Update stopped working. This was from a Rackspace Cloud Server. I cannot imagine what kind of tunneling is taking place in various parts of the internet with IPv6 getting rolled out (finally).
Oh and by the way, I had trouble uploading this picture with BlogEngine.NET and I saw this article:

I did what the user said (in settings unchecked optimize which minifies) and it solved the problem, however I am on IIS 8 not IIS Express.

This is not going well...
The page size of asp.net had increased when comparing to 2008 R2 IIS 7.5 ASP.NET 4.0
C:\Windows\System32\Inetsrv\Appcmd.exe set config -section:httpCompression -[name='gzip'].staticCompressionLevel:9 -[name='gzip'].dynamicCompressionLevel:4
All of a sudden they got smaller...
This modified the applicationHost.config file.
