Makes sense. What is odd however is that I used to get around 15-20 ms ping at most to the Seattle servers, but like OP it has increased significantly to 60-80 ms since Jan 30.
I can confirm this. On CS 2 I'm getting 61 ms ping to Seattle servers when previously it used to be around 20. Distances physically further than Seattle have lower ping now (ex: Chicago at 30 ms, New York at 47 ms).
