[CenturyTel] Centurylink - random latency spikes

Hi all, Throughout the evening I had been experiencing random lag spikes as I was trying to game (nothing more frustrating than 50ms to 600ms). I decided to keep an ongoing ping throughout the night, and this is what I have found: Reply from 74.205.62.55: bytes=32 time=49ms TTL=118 Reply from 74.205.62.55: bytes=32 time=49ms TTL=118 Reply from 74.205.62.55: bytes=32 time=49ms TTL=118 Reply from 74.205.62.55: bytes=32 time=48ms TTL=118 Reply from 74.205.62.55: bytes=32 time=49ms TTL=118 Reply from 74.205.62.55: bytes=32 time=48ms TTL=118 Reply from 74.205.62.55: bytes=32 time=392ms TTL=118 Reply from 74.205.62.55: bytes=32 time=619ms TTL=118 Reply from 74.205.62.55: bytes=32 time=599ms TTL=118 Reply from 74.205.62.55: bytes=32 time=611ms TTL=118 Reply from 74.205.62.55: bytes=32 time=623ms TTL=118 Reply from 74.205.62.55: bytes=32 time=616ms TTL=118 Reply from 74.205.62.55: bytes=32 time=606ms TTL=118 Reply from 74.205.62.55: bytes=32 time=624ms TTL=118 Reply from 74.205.62.55: bytes=32 time=606ms TTL=118 Reply from 74.205.62.55: bytes=32 time=620ms TTL=118 Reply from 74.205.62.55: bytes=32 time=606ms TTL=118 Reply from 74.205.62.55: bytes=32 time=636ms TTL=118 Reply from 74.205.62.55: bytes=32 time=607ms TTL=118 Reply from 74.205.62.55: bytes=32 time=631ms TTL=118 Reply from 74.205.62.55: bytes=32 time=614ms TTL=118 Reply from 74.205.62.55: bytes=32 time=628ms TTL=118 Reply from 74.205.62.55: bytes=32 time=612ms TTL=118 Reply from 74.205.62.55: bytes=32 time=619ms TTL=118 Reply from 74.205.62.55: bytes=32 time=643ms TTL=118 Reply from 74.205.62.55: bytes=32 time=615ms TTL=118 Reply from 74.205.62.55: bytes=32 time=650ms TTL=118 Reply from 74.205.62.55: bytes=32 time=49ms TTL=118 Reply from 74.205.62.55: bytes=32 time=49ms TTL=118 These spikes happen randomly throughout the evening and lasts anywhere from 50 pings to about 500 pings. The century link team told me they guarantee speed but not latency. Is there anything I can do? thanks
