Ping Issue

idk if this happening to anyone else but if not then can anyone explain me wut happen to my ping.

I live in the UK with pretty good connection! i get 14 ping in UK server and 96 in Alpha constantly. But lately my ping acting weird :(

My ping wul switch/jump from 96 to 165 after couples of games..so for example, the first 3 games it wul be 96 the next 3 or 4 game it gonna be 165 then back to 96. Im pretty sure its not a spike cuz nobody using my internet and i have the cable connected so it can't be spiking.
