DDoS Attacks while on Servers?

I've experienced multiple games in HUT and EASHL where even on servers a DDoS is still definitely possible and it's frustrating. It's the same gamertags and obvious within my log on my router adding up exactly with the timeline of the gameplay. I would like somewhere to send the proof of this over to EA and also very confused how that's even possible on these servers. I am on the West Coast server if that helps. Thank you in advance.
