As I said above, Supernews simply resell Giganews. Since Giganews is the largest and most advanced NSP, and has been for a long time, a few more subscribers via Supernews really aren't going to make any difference. The Giga backhaul spreads across three continents and has masses of redundant bandwidth, moreso than any other provider. I've been with them (Giganews/Supernews) for years and have never seen any such slow-down.
I pulled about 50GB last night at 6MB/sec without a problem, so either Giga had a temporary localised glitch, or else your connection had an issue. It's always worth dropping Supernews a line when such things occur, as their support's fast and helpful.
