租用國外虛擬主機(Virtual Host)，因為CPU或是記憶體限制，往往流量訪客數一多，很容易超過使用限制，系統就會被停用。
如果遇到兩光的虛擬主機出租公司，不幫你找出問題，讓你想辦法解決，租用到這樣的主機，只有花錢找氣受。
由於網頁設計公司，租用的是國外主機，客戶朋友的公司沒有專業的人才可以使用英文與國外客戶直接討論虛擬主機相關的問題。客戶說他使用國外主機經驗非常的好，沒有出過什麼問題，介紹由本工作室協助處理。
整個處理的對話如下
Phil: [2:31:21 PM] Hello Johnson! Thank you for contacting midPhase Shared Technical Support! My name is Phil, how can I help you?
Johnson: [2:31:21 PM] Suspension
Phil: [2:31:54 PM] It looks like our admins sent you a notice in Ticket #26077799
Johnson: [2:31:57 PM] could you help me find out the CPU over usage program?
請求他們幫忙找出有問題的地方
Phil: [2:32:09 PM] That your account was suspended due to overusing CPU resources.
Johnson: [2:32:11 PM] yes, I got the ticket.
就是收到停權的通知信，才要要求回覆服務
Phil: [2:32:45 PM] It appears that the PHP coding that you have on your site was overusing the CPU resources.
Johnson: [2:32:59 PM] please resume my account , and help me find out the over usage program, then I tuning it.
Phil: [2:35:44 PM] Your account is now un-suspended. You will need to reply to that ticket within 24 hours and let our admins know the steps you have taken. If you do not they will suspend the account again.
叫我們改善，不然24小時後會再鎖一次
Johnson: [2:36:22 PM] Is there any report help me to find out the issue.
再次請問他們有什麼沒有找到CPU超出限制的報告
Phil: [2:36:46 PM] They provided this information:
[2:36:46 PM] User Domain % CPU ? Process
hXXXXX xxxxx.com 64.0 [php]
hXXXXX xxxxx.com 62.0 [php]
hXXXXX xxxxx.com 60.0 [php]
實在有夠小白的，通知信上已經寫過了，貼這個給我，根本一點用處也沒有
Johnson: [2:37:17 PM] I see the information , but it not help me.
Phil: [2:37:27 PM] And you can use the resource usage tool within cPanel as well.
跟我說控制面版有資源工具可以用
Johnson: [2:38:24 PM] let me check it.
[2:38:55 PM] Thanks.
原本想說，我再花時間看好了
Phil: [2:39:55 PM] Is there anything else that I can assist you with today?
Johnson: [2:40:27 PM] hold on please
後來我直接登入，請他稍等
[2:41:00 PM] I only see the resource usage overview.
[2:41:42 PM] But, how do I use it to find out the program.
[2:42:18 PM] It only shows me the cpu / memory but no program information.
後台的程式，只有顯示出CPU和記憶體的使用情況，並沒有告訴你哪一隻程式有問題
Phil: [2:43:31 PM] Unfortunately we do not have a program that shows you such detailed resource information.
神奇的是，他回答，他們沒有程式可以做這樣的事
Johnson: [2:44:20 PM] if so , how can I improve my program ?
那我們要怎麼找出有問題的程式，並且改善他？
[2:45:43 PM] I don’t know the program which has issue. Then your company made me no choice.
Phil: [2:46:44 PM] You will need to look at your PHP code and programs and see what could be causing it. If you can’t optimize it you may need a VPS or dedicated server.
Johnson: [2:47:34 PM] There more than 3K programs, and you let me check all of then?
這個網站上有3千多隻程式，叫我一隻一隻找嗎？就算24小時不睡覺，不眠不休的找，也不見得看的完所有的程式吧？
[2:48:16 PM] I will try to find out the issue.
後來實在沒有辦法，只能靠自己了
如果您是網頁公司，結果用了這樣的寄存主機，出了問題，虛擬主機商不幫你想辦法，只能自己處理，最後還是有可能落的帳號被鎖的下場，最後服務中止，連備份都來不及，那可就糟了。如果您是一般公司行號，網頁委外設計製作，根本不知道網頁設計公司使用了什麼主機；或是網頁設計公司已經解散倒閉，根本找不到人服務，變成網路主機孤兒。
大部份的虛擬主機商，或多或少都有超賣，如果您的CPU使用超量，您就不是他們的目標客戶，虛擬主機商他們只會要求您買貴的要死的專屬主機。
本工作室，使用國內外虛擬主機長達十年的經驗，可以推薦使用國外優良主機，不再受CPU和記憶體的限制，如有需要，請與本工作室聯絡。
