Well... aol is barely a "partner" of time warner (allegedly)
roadrunner (tw) is only with aol so that they can have AOLs "Security" programs.

BUT A month or so before the AOL/Timewarner... thing. Xbox live used to be nearly lag free (for halo2) and the other games were barely lagging.
I would play a match with 16 people and have NO lag.
Now it's barely playable. I have to empty an entire clip of sniper rifle into somebody's head to kill them.
I used to get really fast downloads of at least 1 mbps from servers nearby that let me

(my computer sucks... usb1.0)
Now I get 170kbps... if i'm lucky.
