It seems that we’re experiencing weird web and mail server problems today. The web site is accessible again, but now the mail server processes are down. We have informed the data center staff and we hope that they’ll be able to fix the problems as quickly as possible. But, if you’re sending email to us today and never receive an reply or a bounce, we’re not ignoring you intentionally — please simply re-send it in two days. Sorry for the inconveniences.
Addition: Reply from data center received. The server had internal errors and restarted a few times. It’s stable and the night watch keeps an eye on it. The day staff will look into what happened and correct the problems.
