Why is my Ping so High

Today when i got onto crossfire i saw my ping was at 60 im confused because the day before it was at 9 - 13 i got on my bros PC and it shows he has 9 ping when we play together on the same connection i get a much higher ping... I went on speedtest.net and got this from the west coast server
Ping - 11
DL Speed- 25Mbps
Upload - 24Mbps
Why is my ping so high in crossfire but for every thing else including Bc2 and Black ops my ping is normal
