Weird lag problem/bug?

I have a steady latency of 160 when im on hideout/most maps, but for some reason in some maps it goes up to 300 ~ 900 and keeps dc'ing for several seconds from time to time, its not my internet since it stays like this for as long as im inside said map, if i go back to my HO it instantly goes back to 160 ms, is anyone else having this problem? (it also happened on my vorici daily instance)
