I have an overloaded node in my area as well. I have been struggling with cox for 6 months with no end in sight. I too upgraded to gigablast hoping that it would help. I think my situation with ping and packet loss got worse. Cox has sent three techs out, they all had different reasons for the issue; solar flares, coronavirus traffic and overloaded node. I went to a friends house (he has cox 150) with my laptop and gaming was perfect. I wish they could get everyone's issues fixed. I cant even game anymore, the lag makes me sick to my stomach.
I have the same issue. File a complaint with the FCC, its the only way to get cox to pay attention to your issue.
