這一兩天原本租用的HostMonster虛擬主機連線不穩定，推測應該是從台灣連到美國中間的「p6-0-0.RAR1.LA-CA.us.xo.net」這個點會爆掉，之前已經發生過好幾次類似的狀況，而且寫信給HostMonster主機商或「xo.net」這家公司都得不到啥回應。
因為也不知道該怎樣解決，最後可能得再換主機吧，考慮中…。最近看網路上很多人都推薦Site5這家虛擬主機，寫信問了他們CPU Time與相關的使用限制如何，，
說實在的，限制還真的很多。不過至少比其他家虛擬主機商好一些，他會鉅細靡遺的全部列出來，不像其他家什麼都不講，踩到線就直接停權。有些主機商寫信去問也不跟你講啥，頂多只講了10%、20%，怎麼處理也不講，Site5至少算清楚一些了。
看樣子，應該是最後一次用虛擬主機了，再換的話就得考慮VPS或專屬主機（Dedicated Server）嚕，真想玩玩呀。
