Well, I am still here! To make a long story short, the company that was in charge of maintaining my DNS entry (essentially a “phone book entry” between the name “jastram.de” and the server’s number) screwed up big time. The screw-up was caused by the acquisition of the hosting company and the migration to new servers. Roughly 500 domain names were affected, but most of them were restored within a few days. Just with my account everything that could go wrong went wrong.
