Really?

I see there a www.google.de so it's all perfect.

But google has many IPs and servers:

# host www.google.de
www.google.de is an alias for www.google.com.
www.google.com is an alias for www.l.google.com.
www.l.google.com has address 209.85.135.104
www.l.google.com has address 209.85.135.105
www.l.google.com has address 209.85.135.106
www.l.google.com has address 209.85.135.147
www.l.google.com has address 209.85.135.99
www.l.google.com has address 209.85.135.103

So maybe not all have the same certificate or configured as the same.
