I have this problem since the past 10 days.. (school holiday I suppose)

Normally I would ladder on NA because my friends are all there.. I'd played 1v1, 2v2 and 3v3 with my friends no problem.. I'm using Streamyx and been playing multiplayer on NA server since February without serious lag spikes, except the 0.5-1 sec delay depending on the time I playing.

So now I'm getting serious lag spikes when playing 1v1.. like 1-2 seconds freeze, and then everything fast forward to catch up with what is seen on the opponent's side.. does anyone else having the same issue when playing on NA?

P/S: I have no problem playing on SEA server. I've always been using the SEA client to play on NA server.
