 ## Information
 
+One thing I discovered while analyzing this problem is how slow a test windows server performed, especially when trying
+to run the AWS Test scripts.  I found that the proxy settings were incorrect, only set to ignore 169.254.169.254 and *.ead.census.gov,
+which is not valid. A more comprehensive proxy setup, ignoring what it should be (*.census.gov among many others) improved
+the performance **drastically**.  This change will ultimately get rolled into all of the Windows builds and into the GPOs
+accordingly.

 * dig for csp1.ead.census.gov
