Ooops.... Forgot to post the rest of the story here... Well, as I said, I immediately contacted DreamHost and started investigating my download logs. It seemed just a couple of users were using several percents of the total number of downloads: leechers/DDoSsers. That's the reason why there were >200 simultaneous downloads. I've just banned their IP's and now the server is running very well again. DreamHost was pleased with my fast response so banning my account won't happen either, I think. Plenty of bandwidth, that wasn't the problem, just too much (unnecessary) load, which is fixed now. In the future it won't even possible, thanks to my own download distribution system, which is already partly finished. But now my attention goes to the new DriverPacks BASE, of course.
