My server was dead. Not even a little blink from one of the many LEDs in the system or some other sign of life when putting the power on it. So I figured that replacing parts would be like a puzzle. Is it the power supply? The motherboard? The CPU? Or a combination of any of the parts? Replacing one of them would easily cost me about 100 euro. So I did some math, and figured that hosting was not only a relatively cheap solution, it also has many advantages (that all of you IT people can list better than me).
I went with DirectNIC, since I have been using their services for over 15 years now.
And as you can see, it just works. I had to do some work to restore the WordPress database, since the last backup I had on my NAS disks was from the end of 2015. But with some diskswapping, file copying, MySql-dumping+importing and WP-CONFIG changing it now works.
