Same here. I use Yousee which is a subsidiary of Teledanmark. I have had the problems before (as has other Teledanmark customers), if it is like last time it is router problems somewhere between us and the server location (try to do a traceroute and see where the ping starts jumping), affecting both Teledanmark and probably also Telenor. Mine started jumping when entering Germany.
Our ISP can't or won't do anything if it outside their area, and the server host will most likely just say it it is a momentary hiccup, and that we should be patient. But I gave up on the German website last time I tried to file a complaint.
