Ok so I have ISDN, some of you in europe know what that is, but for those who don't it's a special high-speed phone line. I get 64k per line and I have 2. SO here's the deal, a few days ago I am playing cs and my ping goes up to 600, holds for a second, and then goes back down to 70-80. It does this the entire time I'm playing up and down and up and down. I don't know if it's because I am only using 64k and not the entire 128k but I'm pretty sure I didn't use 128k before. Even so, if I had a too slow connection (64k) wouldn't the ping stay at 600? Is this just because my internet is too slow, a steam problem where it's doing some other fucking thing while I'm playing, or is my ISP being flakey?
