I'll kill those incompetent admins!!!
The address https://web.archive.org/web/20060415181401/https://radio.super.lv doesn't work everywhere - and it's all because of the LU Institute of Mathematics, which is in charge of our DNS names. They think they're so damn smart and configured everything in violation of the standards. Plus they don't answer emails, you have to call them.
UPDATE: I'm the idiot. Turns out, when changing the ip address of the DNS server responsible for the zone, you have to change some authorization code for security, at least here in LV. I guess the super.lv admin will come by this evening, fix it, and I'll be a happy camper.
