Website was down for a few hours, deu to a glasfiber modem upgrade. Server seems happy after his first reboot in 2.5 years 🙂
KPN routers force their users to use 192.168.2.xxx IP range (with a 255.255.255.0 subnet mask). So it took me some time to get all my 192.168.0.xxx devices to the new enforced 192.168.2.xxx range.
