Holy crap the game lags!!!!

Much more rarely and the intensity of the spikes lowered quite a bit but it still does happen every now and then, in my case its generally late at night past 2am most of the time. Even if the lag spikes frequency are a lot lower, as soon as one happen, the game become  slower as if in a continious delay and high ping until the next whistle then it kind of reset fresh....Until more happens. 
It barely happens compared to what it used to be but last time I played (last friday)' I still got a few occasionally.
