Game randomly freezes/lags

i have a 20-22 ping, my game literally never has done this before these last 2 patches and now it's doing it all the time; randomly just hits these huge lag spikes and then returned to normal.

What's going on? Is there something that I can do to fix it? It happens so often now i'm almost getting use to it but it's still frustrating that it does this and when i die it makes me not even want to play cause i know it'll just spike again and a random time
