I am in Chicago on Comcast and my link has been all over the place in quality sometimes being great and sometimes being nearly unplayable in any way. The last 2 days I noticed a weird jump in ping on the last hop that my friends on other isps do not get. Very early in the morning it seems to be fine at 45ms, but later in the day it jumps to 110ms till very early in the morning again.

Trace complete.

The last 3 hops are the same IP's for my friends and I, but only I am experiencing the jump in ping from .234 to .40

When it's only 120ms it is still playable, but sometimes the game gets so bad everything freezes then rubberbands and commands won't go through.
