World ms on raids and battlegrounds

I can play normally with 60-70 ms but when I enter a battleground or a raid I get 400 to 5000 ms and its unplayable! I thought it was my problem and deleted the game and installed again. I still got the same issue and it only happens in World of Warcraft. Other games don’t have this. Please solve this issue asap…

Been like that all day.
