I think you might have been confused by the fact that the new logo is basically just a polished-up version of the original one. Were you expecting the gopher at that URL?

Yes, I was expecting the gopher, especially because of the URL's path including the word gopher. Looking at the wayback machine shows you're right, this is the same picture that's been at that URL for years. I just always thought of the gopher as their logo, didn't realize there was another logo they used (I don't use Go so not too familiar with it).
