This is just a message to tell you that there will be some interruption to the connection to this server. Monday 19th I will change ISP (bye Demon, hello TweakDSL), so I need to change my DNS settings and they will have to be propagated. That will take some time.
For your information: the linespeed will change from 6016/1024 to 10240/1024. Some, more downloadspeed for me. And more money, since TweakDSL is cheaper than Demon is.
