I couldn't get to the 1st link either, but in my case, I knew why. For whatever reason, MS decided to run the link via atdmt.com
"http://clk.atdmt.com/MRT/go/141861415/direct/01/?href=http://go.microsoft.com/fwlink/?LinkID=142198"
My HOSTS file blocks atdmt.com because they issue cookies that can follow your web travels...
