Weird Gmail Error Message

I'm getting the following error message here in Germany when I go to gmail.com. Anyone know why that is? It's also mentioned here.

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.

Update: here is a link that explains it, thanks to Wenjun's Mom.
