High Latency spike every 10 min or so causing problems with gaming

For the last 3 months every 10 min or so I have server lag while gaming.  When I do a ping test I noticed that a packet would spike at 2800 ms every 10 min or so while my average was 10ms the

rest of the time. I took my computer to work which has At@t fiber and tried the ping test for 60 mins and no latency spikes.  How do I schedule a tech to come out to resolve the issue ?
