CosmicRhinoceros, century link fiber, NA West. It seems entirely random. It will happen a few times each match at random times, sometimes in the middle of fighting someone, other times while just walking around looting. For a few seconds it spikes to 300+ then drops back to 20 after stuttering. The only thing I noticed as a pattern is that it happened with higher frequency during teams of 33s. But it still occurs almost every game across other game modes.
I've been reporting this using the in game feedback function a lot, not sure if that helps. I haven't noticed packet loss.
The same thing happens at my friends house across town, both ps4 at his and my place.
The in-game feedback is actually invaluable since it uploads your client logs. With your account name I can have the team search for your logs and we can take a look.
No promises I'll be able to report back directly, but definitely going to check into this to see if there's anything systemic going wrong!
