Ahhh but OOL isnt national like @home is... the farther away from "home" OOL goes, the less control they will have. But no, thats not the only reason I think @home keeps their UL so low. They are trying to squeeze as many people onto a node that they can... there is far more downstream available than upstream. Therefore the low cap. There is much more downstream bandwidth to spread around.
OOLs system is much smaller than @home, so of course, its much easier to maintain it and keep it in tip top shape.
Im not necessarily justifying @homes practices (low UL cap, overselling nodes), but I cant say I can complain either, because I knew well before I signed on about the UL cap. -- iTunes or noTunes!
At the time I signed up I knew far less about speeds than I know now and I was anxious to get rid of my 56k. I love the download speeds but I am very disappointed in the low UL cap. It's absurd that they try to oversell nodes. I email them about it and sometimes they don't respond or other times they send me an email telling me how to optimize my speed when I've already done all of that. If they don't raise the UL cap soon I'm going to switch over to DSL.
