New hosting provider
As of today, this web site runs at a new hosting provider: Host Delight, a company of Dolf Schimmel, who is a friend of mine.
Only one problem occured with the transition: all the links on the Links page are gone. Somehow they didn’t survive the WordPress export/import process. I’ll try to recover those from my database backup.
Otherwise, everything went pretty smoothly. All in all, my web site was down for less than two hours. Some users might still be seeing my old web site because their DNS cache hasn’t yet been updated, but that should last no more than 48 hours.
Update: I managed to import the links from a database dump, so now my web site is 100% functional again.
