Taking in to consideration that each cable modem user probably won’t be pulling nearly half that (in a good design, they shouldn’t need to anyhow), we’re still left with the capacity for only 660 or so users, each getting sub-100KB/sec rates. Factor in all the other users who will want to be downloading CS from LANs, DSL lines, modems, and other connections, and we’re talking about a massive number of people. For comparison’s sake, at about 9pm Wednesday, there were nearly 70,000 people playing CS. If even one out of every 10 of them try to update CS, that’s 7,000 people all hitting Steam at the same time, and most likely the numbers will be higher than that. 500 megabits isn’t nearly enough to feed that kind of hunger.
