Sorry folks, but this weblog was unreachable for a couple of days. I could not find out why, because I did not change anything. Like a configuration on the server, or something on my router. I restarted some of the processes, like Apache and my nameserver, but only to find that the situation did not improve.
Until I found out yesterday that my ISP for some reason at some point in time (probably the 19th) decided that my dedicated IP-address needed a change. That’s why the client requests a dedicated IP-address, isn’t it?
So I changed the nameserver configuration, changed the nameserver pointer at DirectNIC, and things should be in working order now. Let me know if you experience strange behaviour.
