Intermittent Ping Spikes on the 2nd Hop

So recently I've been having issues with intermittent ping spikes on all devices connected to the internet in my house. I began to run traceroutes to try to identify the issue and have noticed that the 1st hop (connecting to the router) seems to have no issues as that time is always <1 ms, but then from the 2nd hop onwards there are occasional ping spikes from anywhere between 100ms all the way up to 500 or 600ms. The ip address on the 2nd hop is always the same, so I assume this is some sort of Cox device, but I have no idea which one it is in particular. Does anyone know which device this would be?
