Google's www2 and www3 sites are broken

Recently I noticed a peculiar activity on the www2 and www3 google datacenters, Both of them redirects to google.com, So why is this happening, As usual many people in top SEO forums predict there is a big update coming on, They think probably google is testing their new data there and hidding it from us,



But my opinion that is not the case, Goolge took away all the other datacenters from us before 10 months now they removed this too, They probably think they are helping webmasters/SEOs too much, Probably they want to reduce a huge manipulation on their search results, We have to wait and see,
