Sorry folks – I owe you an apology …
My domain wolfgang-ziegler.com expired yesterday and so this blog had been offline for a couple of hours. It seems I have been relying a bit too heavy on email notifications (which I did not receive) so the domain expiration went unnoticed.
This should not happen again since I already created an Outlook reminder for 2015 :).
[BTW: My other domain wolfgangziegler.at was functional though during this time.]
