In Germania digitando gmail.com sul browser, spunta questa scritta:

We can’t provide service under the Gmail name in Germany; we’re called Google Mail here instead.
If you’re traveling in Germany, you can access your mail at http://mail.google.com.

Oh, and we’d like to link the URL above, but we’re not allowed to do that either. Bummer.
For general information about Google, please visit www.google.com or www.google.de.

Chissà perchè?
