Las Vegas Internet Lag - Reoccurring issue

I just came here to complain about the same issue.  I had the 300mbps service in Las Vegas, and just downgraded because why bother if I'm getting crappy ping/latency while gaming?  If you do a tracert to the destionation IP (in this case, LoL NA is 104.160.131.3), you will notice that things are nice and fast until they hit Cox infrastructure.  In this case, it will hit 72.215.224.162 (a Cox internal gateway/load balanced network device) and immediately spike to 60+ms.  Example:

Tracing route to 104.160.131.3 over a maximum of 30 hops

  6    60 ms    61 ms    61 ms  72.215.224.162    <------ the offending IP
  7    61 ms    67 ms    65 ms  104.160.152.223
  8    62 ms    61 ms    60 ms  104.160.152.227
  9    67 ms    70 ms    70 ms  104.160.159.100
 10    68 ms    67 ms    68 ms  104.160.131.3

This is because Cox is downright dishonest and is filtering/throttling certain services.  Unfortunately they've brokered a monopoly in my area and I can't just cancel them.  I'd suggest dropping them and going to Centurylink if you can get their fiber broadband.
