Net Applications reported this week that one third of the traffic coming from Google’s facilities has no user agent. This report refers specifically to the traffic coming from Google’s employees and not the Search Engine’s traffic.
Vince Vizzaccaro, a senior executive from Net Applications said that they had never seen an OS stripped off the user agent string before. “you have to arrange to have that happen, it’s not something we’ve seen before with a proxy server.”
So what’s Google hiding? Of course, Google, like Google wouldn’t comment on rumors and speculations.

What do you think? Why would they hide their UA?
