Extreme packet loss when playing ranked on Xfinity internet

Hello! Day one player here, who has played on both Playstation and PC since the game launched on Comcast/Xfinity at the same address in central New Jersey for years. I haven't had much lag in that time, but recently, since the server update and anti-DDoS implementation, whenever I am connected to a secure server in ranked (with the pentagon icon in the performance data bar), I get extreme packet loss (all of the red icons) to the point of the game being unplayable. This has only started to occur in the last several months and is incredibly frustrating. 

I've seen this issue raised in several other locations before. Here's a thread on the Xfinity support site about this, and another one on their site. All of the symptoms described there are happening to me as well, and it seems like this is primarily impacting NJ customers. I've done everything I can to remedy the situation on my own - new router, new modem, new cables, tried both PC and Playstation - and the issue persists. There's wide speculation that this is occurs primarily due to some bugged interaction between the Xfinity network and EA servers. 

Is there any chance that an engineering team can take a look at this problem? No one I play with on other ISPs seems to be having this problem. I don't even have the option to switch ISPs where I am, so until this issue is resolved, ranked is literally unplayable for me. Please let me know if you have any questions. Thanks for your help!
