Help With My Connection

Hey Z8,
I need a little help with my connection. I hope there will be someway to fix it.
It's about my ping (status). My ping is perfectly good in WestCoast(11), in Alpha and others is 70. But sometimes, my ping spike to 1000 :O. It bug me so much. So are there anyway to help me fix it.

The spike lag has gone down to 400-900 now. But the pace is like 1 time per 1min.

Help please.
