逆向行駛 最愛的最殘酷、最美的最虛無
剛在LowEndBox看到Avante Hosting提供了一個滿不錯的特惠，租了一個KVM Copper VPS的方案來玩玩看，主機位置在美國東岸，可能目前比較少網友進駐所以編譯速度還不錯 ?

*********記錄更新 o.o*********
KVM安裝粉慢，都快超過1小時，後悔 = =… ? 不過還好發個TICKET請他們幫忙換成XEN方案通過哩! 服務讚唷 ?
再補個traceroute圖片，從這可以大該猜到應該是代管在HostDime這家主機商，希望他們是COLO過去的，不然那摸低價，偶也很怕他跑路ㄟ ㊙️
買了一個，速度還好~ 當DNS用! ?
